<span style="font-size: small;">The OSPF Type-4 LSA is perhaps most misunderstood subject with honors to OSPF for folks that are just or halfway learning the protocol. I was going through one of the blog which explain the same OSPF Type-4 LSA & in comments one of the individual asked that “How ABR will come to know that when to generate Type-4 LSA ?”</span></div>
<div class="MsoNormal" style="font-family: Verdana,sans-serif;">
<br /></div>
<div class="MsoNormal" style="font-family: Verdana,sans-serif;">
<span style="font-size: small;">Interesting question & then I decided to illuminate more on this & also we will take a look at OSPF Type-4 LSA.</span></div>

<span style="font-family: "Lucida Calligraphy";">“Type-4 LSA - This is the ASBR Summary LSA this basically identifies the ASBR of a specific area (note that inside the area where the ASBR is this LSA will not exist, instead the type-1 LSA will be used in order to announce the ASBR of the area). Who is the ASBR of the area? The type-4 LSA is there in order to answer this question, so this is injected by the ABR in order to announce the presence of the ASBR in a particular area.”</span></div>

<div class="MsoNormal" style="font-family: Verdana,sans-serif; margin-bottom: 0pt;">
<span style="font-size: small;">When we redistribute any routing protocol in OSPF domain then that router will generate Type-1 LSA and inform all routers within an area that “I am AS boundary Router” with Flag - E bit on . So the ABR will come to know that we have ASBR & then ABR will generate Type-4 LSA towards other areas which are connected to ABR. </span></div>

connection lever profile, based on UDP, FastL4 or TCP profile type. Thus if you
have not assigned any profile then LTM adds a default profile (UDP, FastL4,
TCP) depend on Virtual Server protocol
setting , If you have selected UDP then it will add UDP profile or if you have
selected TCP then it will add FastL4 Profile. ( Types of profile are mention

<div class="MsoNormal" style="margin-bottom: 0.0001pt;">
<b><u>Overview: </u></b></div>
<div class="MsoNormal" style="margin-bottom: 0.0001pt;">
<br /></div>
<div class="MsoNormal" style="margin-bottom: 0.0001pt;">
Health monitor test the availability of devices and services on the
network and are used to determine whether pool member are working properly,
Monitor test the availability of member based on criteria defined by
administrator. Usually we test the availability of network devices using ICMP
protocol but we cannot verify accessibility of application using ICMP protocol.
So to resolve this issue we can use application based monitor like we can
monitor HTTP, TCP or any port that is used by particular application or we can
send request to that particular port to get expected response. So in this way
we can monitor the availability of applications and also we can assign multiple
monitors to node, member or pool to verify availability of applications.</div>
<div class="MsoNormal" style="margin-bottom: 0.0001pt;">

<div class="MsoNormal" style="margin-bottom: 0.0001pt;">

whether an IP address is reachable. When a monitor associated with a node is
unsuccessful then that node will be marked as an OFFLINE.Usually these types of monitors will use ICMP to determine
availability of node.</div>
<div class="MsoListParagraphCxSpMiddle" style="margin: 0cm 0cm 0.0001pt 76.5pt;">

a service is available by opening connection with IP address and port. The TCP
monitor is an example of this type of check.These monitor will report UP when TCP connection is
establish with particular IP and port then it will close the connection &
if TCP connection is not establish then it will report OFFLINE.</div>

like they also test whether the server is serving appropriate content which
make sense, for example if you have setup HTTP server and you assign monitor
which will test HTTP port but might be there could be error with HTTP content
so service checking monitor cannot identity these error. So content checking
monitors will help you to verify the appropriate response from particular
server.<span style="text-indent: -18pt;">The monitor will establish TCP connection & then issue a command to
check the response from server. i.e. for HTTP
it will issues GET / command .</span></div>

information, with configuration parameters present to provide a level of
disambiguation.</span></li>
<li><span style="font-family: 'Courier New'; text-indent: -18pt;"><span style="font-family: 'Times New Roman'; font-size: 7pt;"> </span></span><span style="text-indent: -18pt;">“</span><b style="text-indent: -18pt;"><i><u><span style="color: #e06666;">List</span></u></i></b><span style="text-indent: -18pt;">” provides
actual configuration information, but just variations from the default. For
example, “</span><i style="text-indent: -18pt;"><span style="color: #e06666;">list /ltm virtual TEST</span></i><span style="text-indent: -18pt;"> will
show you the configuration.</span></li>

a “list” command to show every configuration option, not just the variations
from default.</span></li>

command is very useful if you are not familiar with CLI mode of TMSH. To use
“HELP” command just uses the same structure mention above. For Example: “help
ltm pool” this will show you all detail CLI syntax, description, configuration
example & related options with their descriptions.</span></li>
<li><span style="text-indent: -18pt;">“</span><b style="text-indent: -18pt;"><u><i><span style="color: #e06666;">Save</span></i></u></b><span style="text-indent: -18pt;">”

The Switch Module, where all application delivery traffic enters and
exits, connects to the PVA (Packet Velocity ASIC), F5’s custom-engineered L4
load balancing ASIC switching fabric. Traffic that can be handled within the
PVA never goes any further; at this step, all packet and connection management
occurs at the hardware level by the PVA through the Switch Module. Traffic
enters through the switch into the PVA, where the appropriate logic and
transformations are applied before the traffic is sent back out through the
Switch Module. Generically speaking, this is typically referred to as the
fastL4 profile. For traffic and which is
not handled by the PVA, it is simply passed through the PVA onto the next
layer, which F5’s primary traffic management processing system is called TMM
(Traffic Management Microkernel). TMM handles all of BIG-IP’s local traffic
functionality such as intelligent load balancing, compression, SSL, iRules,
packet filters, etc. (with the exception of L4-only load balancing, which can
be handled in either the PVA or TMM). The TMM can manage traffic using several optional hardware acceleration modules such as SSL, FIPS, and
Compression and has entirely dedicated hardware. TMM is also responsible for
delivering traffic to the Host Management subsystem as necessary for products
such as BIG-IP Global Traffic Manager (GTM).</div>

<b><u>Historical Overview: - </u></b></div>
<div class="MsoNormal" style="margin-bottom: 0.0001pt;">
<br /></div>
<div class="MsoNormal" style="margin-bottom: 0.0001pt;">
Historically, there have been two ways to build Application Delivery
Networking </div>
<div class="MsoNormal" style="margin-bottom: 0.0001pt;">
Appliances—build them for performance or build them for intelligence.
In the open market, customers have traditionally selected solutions that
exhibit the best performance. As a result, most vendors have built their
devices on faster, packet based designs instead of the poorer performing
proxy-based architecture. As the need for intelligence in these devices has
grown, vendors find themselves in a precarious position: the more intelligence
they add to the devices in response to </div>
<div class="MsoNormal" style="margin-bottom: 0.0001pt;">
Customer demand, the closer they resemble a proxy and the worse they
perform.</div>
<div class="MsoNormal" style="margin-bottom: 0.0001pt;">
<br /></div>
<div class="MsoNormal" style="margin-bottom: 0.0001pt;">
F5 initially took the packet-based path, but simultaneously started
addressing the root problem—making an intelligent solution that also delivers
high performance. The result is the F5 TMOS® architecture, a collection of
real-time features and functions, purpose-built and designed as a full-proxy
solution with the power and performance required in today’s network
infrastructure.</div>

<div class="MsoNormal" style="margin-bottom: 0.0001pt;">
TMOS is the universal product platform shared by F5 BIG-IP products. No
single competing technology can solve such a wide variety of application
delivery problems over networks.</div>
<div class="MsoNormal" style="margin-bottom: 0.0001pt;">
With its application control plane architecture, TMOS gives you
intelligent control over the acceleration, security, and availability services
your applications require. TMOS establishes a virtual, unified pool of highly
scalable, resilient, and reusable services that can dynamically adapt to the
changing conditions in data centres and virtual and cloud infrastructures</div>

purpose-built, custom architecture which F5 spent years and significant
investment developing as the foundation for F5 products going forward. From a
high-level, TMOS is:</div>

<h2>
Cisco Nexus 2000 Series Overview : - Fabric Extenders </h2>
<br />
<span style="font-family: "Trebuchet MS", sans-serif;">Cisco Nexus® 2000 Series Fabric Extenders have transformed data center designs and enabled data<br />center architects to gain new design flexibility while simplifying cabling infrastructure and reducing management complexity. Cisco Nexus fabric extenders act like remote line card which which gives you design flexibility for your data center.</span><br />
<br />
<span style="font-family: Georgia, "Times New Roman", serif;"><span style="font-family: "Trebuchet MS", sans-serif;">Fabric extender work with parent nexus switches i.e. N7K , N5K & Cisco UCS. Fabric extender work as additional remote line card for parent switches. All fabric extenders connected to parent switches can be configured from parent itself. Logically it act as one device or you can say as chassis device</span>.</span><br />
<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjAyTcwbJ2vO6xzK-m3x4F4-AYjmKCv9oxr1Rqfo-oIotrHYiLvSkoJs8GW5R4yMF92M4lGAohzjgeu5PE7ATkY7uzqMuuOr9Qx9SQC7CZyTdLE0v7xYpOG0Hwg621sOKnBN31WXUNhxGk/s1600/Cisco+FEX.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="149" qba="true" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjAyTcwbJ2vO6xzK-m3x4F4-AYjmKCv9oxr1Rqfo-oIotrHYiLvSkoJs8GW5R4yMF92M4lGAohzjgeu5PE7ATkY7uzqMuuOr9Qx9SQC7CZyTdLE0v7xYpOG0Hwg621sOKnBN31WXUNhxGk/s400/Cisco+FEX.JPG" width="400" /></a></div>
<br />
<span style="font-family: "Trebuchet MS", sans-serif;">To setup these fabric extender & configuration is very easy, below is the configuration for fabric extenders :-</span><br />
<br />
<br />
<span style="font-family: "Courier New", Courier, monospace;">Nexus(config)# feature fex<br />Nexus(config)# interface e1/10 - 12 (Port Channel for HA)<br />Nexus(config-if-range)# channel-group 160<br />Nexus(config-if-range)# no shut <br />Nexus(config-if-range)# exit <br /><br /><br />Nexus(config)# interface po160<br />Nexus(config-if)# switchport mode fex-fabric<br />Nexus(config-if)# fex associate 160<br />Nexus(config-if)# no shut<br />Nexus(config-if)# exit</span><br />
<br />
<br />
<span style="font-family: "Trebuchet MS", sans-serif;">This is what you need to configure to make your fabric extender to work. Now you can see that you Fabric extender will come online & all fabric extender Ports will be mapped with your port-channel.</span> <br />
<br />
<span style="font-family: "Trebuchet MS", sans-serif;">For Example : Here we had used Port-Channel 160, Now if you want to configure Fabric Extender ports then you need to configure " interface eth160/1/1" </span><br />
<span style="font-family: "Trebuchet MS", sans-serif;">160 is your port channel , 1/1 is your Fabric Extender port.</span><br />
<br />
<span style="font-family: "Trebuchet MS", sans-serif;">Show commands : </span><br />
<br />
<span style="font-family: "Trebuchet MS", sans-serif;">@ sh run fex </span><br />
<span style="font-family: "Trebuchet MS", sans-serif;">@ sh fex detail</span><br />
<span style="font-family: "Trebuchet MS", sans-serif;">@ sh int po160 fex-fabric </span><br />
<span style="font-family: "Trebuchet MS", sans-serif;">@ sh module fex</span><br />
<span style="font-family: "Trebuchet MS", sans-serif;">@ sh int status fex 160</span><br />
<br />
<span style="font-family: "Trebuchet MS", sans-serif;">Also you can connect this fabric extender to separate Nexus switch & create VPC's for HA. For that you need to config VPC's under port-channel & also you need to configure VPC's domain & peer link between both nexus switches. Below is test scenario for same : </span><br />
<br />
<span style="font-family: "Trebuchet MS", sans-serif;"> Nexus Fabric Ext</span><br />
<span style="font-family: "Trebuchet MS", sans-serif;"> = =</span><br />
<span style="font-family: "Trebuchet MS", sans-serif;"> = =</span><br />
<span style="font-family: "Trebuchet MS", sans-serif;"> = =</span><br />
<span style="font-family: "Trebuchet MS", sans-serif;"> = =</span><br />
<span style="font-family: "Trebuchet MS", sans-serif;"> N5K-1 ========== N5K-2</span><br />
<span style="font-family: "Trebuchet MS", sans-serif;"> vpc peer link</span><br />
<h4>
</h4>
<span style="font-family: "Trebuchet MS", sans-serif;">In this type of design is highly recommend because of redundancy. In next post i will come up with Virtual Port Channel known as VPC's.</span><br />
<span style="font-family: Courier New;"><br /><br /><br /><span style="font-size: x-small;"><br /></span><br /><span style="font-size: x-small;"><br /></span><br /><span style="font-size: x-small;"><br /></span><br /> </span><br />

<br />
From long time the blog was not active due to my work, but now onward the blog will be active & i will come up will all available technologies that is used in Service Provider , Enterprise Network & Data Center which include Routing & Switching , Security , MPLS , Load Balancer & Cisco Data Center 3.0.<br />
<br />
I will come up with all major IT vendor i.e. Cisco, Juniper, Check Point, BigIP F5 etc.<br />
<br />
As we know that the IT world is changing so rapidly that we can't stick to single vendor & technologies.<br />
Now the Virtualization is the key component for IT Department because it reduce cost & increase productivity.<br />
So the new name of Virtualization is "Cloud Computing".<br />
<br />
Cisco is having very impressive product line for this Virtualization . ( For more detail check www.cisco.com for Cisco Data Center 3.0)<br />
<br />
So Cisco came up with New Certification CCIE Data Center or we can say it is enhance version of CCIE Storage.<br />
<br />
So stick to this blog & get more detail on above technologies.<br />

</div><div>Here i am going to explain you how to save the configuration in CISCO IOU , so that you can have that configured topology any time when ever you want , So now you can review the configuration & use the old configured topology for you LAB practice.</div><div><br />
</div><div>The requirement to save configuration is the same one that we using for LIVE CD, Here we are going to use the Ubuntu OS for GUI mode, But how know the CLI he can go with CLI mode without having Ubuntu OS.</div><div><br />
</div><div>1] Download the Ubuntu OS & install in VMware machine.</div><div>2] Run VMware machine with the <a href="http://u.115.com/file/bw3whane">CISCO IOU TS1 & TS2 Live CD</a> with auto mount option.</div><div><br />

<br />
<span style="font-size: large;"><span style="font-size: small;">You can telnet all router that you are running in Cisco IOU. Please follow the below steps :-</span></span><br />
<span style="font-size: large;"><span style="font-size: small;"><br />
</span></span><br />
<span style="font-size: large;"><span style="font-size: small;">Check the IP address of VMware machine with "ifconfig" command. VMware machine will automatically get IP address because of DHCP, DHCP is enable in VMware so when ever you will run VMware machine the you will get IP address. (Default) </span></span><br />
<span style="font-size: large;"><span style="font-size: small;"><br />
</span></span><br />
<span style="font-size: large;"><span style="font-size: small;">For example your IP address is 192.168.120.110 then open Putty or Telnet or use SecureCRT to do telnet.</span></span><br />
<span style="font-size: large;"><span style="font-size: small;">You will do telnet to IP address : <i><u>"telnet 192.168.120.110 2001 "</u></i> 2001 is the port number.</span></span><br />
<span style="font-size: large;"><span style="font-size: small;"> </span></span><br />
<span style="font-size: large;"><span style="font-size: small;">So you will get R1 prompt , In this way yo can start telnet using port number till 2030 in TS1 & TS2.</span></span><br />
<span style="font-size: large;"><span style="font-size: small;"> </span></span><br />
<span style="font-size: large;"><span style="font-size: small;"> For Example : </span></span><br />
<span style="font-size: large;"><span style="font-size: small;"><br />
</span></span><br />
<span style="font-size: large;"><span style="font-size: small;"><i><u>"telnet 192.168.120.110 2001 "</u></i></span></span><br />
<span style="font-size: large;"><span style="font-size: small;"><i><u>"telnet 192.168.120.110 2002 "</u></i></span></span><br />
<span style="font-size: large;"><span style="font-size: small;"><i><u>"telnet 192.168.120.110 2003 "</u></i></span></span><br />
<span style="font-size: large;"><span style="font-size: small;"><i><u>"telnet 192.168.120.110 2004 "</u></i></span></span><span style="font-size: large;"><span style="font-size: small;"><i><u> </u></i></span></span><span style="font-size: large;"><span style="font-size: small;"><i><u> </u></i></span></span><span style="font-size: large;"><span style="font-size: small;"><i><u> </u></i></span></span><br />
<span style="font-size: large;"><span style="font-size: small;"><br />
</span></span><br />
<span style="font-size: large;"><span style="font-size: small;">Use Secure CRT to save the session , So that you can use those session any time .</span></span><br />

<br />
101:0<br />
101:18 102:2<br />
102:0<br />
<br />
There are two routers represented here, identified by “application ID” values 101 and 102 (which you pass to the IOU images when starting them up).<br />
<br />
The first and last lines represent an interface which is connected to nothing. The second line shows that the interface on 101 identified by 18 is connected to the interface on 102 identified by 2. Where do these numbers come from you ask?<br />
<br />
Unlike Dynamips/Dynagen, “NETMAP” does not use interface names but, rather, interface IDs. The IDs are not tied to a specific interface type (e.g. Serial or Ethernet). When launching an IOU instance, you can specify (via the command-line) which interfaces you want and how many. The ID used for Serial1/2 and Ethernet1/2 would be the same and, as such, it’s impossible to have both of those interfaces in an single instance.<br />
<br />
To calculate the ID used by “interface x/y”, you would use the following formula:<br />
<br />
id = x + (y * 16)<br />
<br />
Examples:<br />
<br />
interface 0/0 = 0<br />
interface 0/3 = 48<br />
interface 1/2 = 33<br />
interface 12/1 = 28<br />
<br />
Based on this formula, we can see that in the second line of the example NETMAP file, 101′s interface 2/1 is connected to 102′s interface 2/0.<br />
<br />
Using this formula (and the resulting values), it should be fairly easily to construct your own NETMAP files from scratch.<br />
<br />
Note that you can’t, unfortunately, “bridge” an IOU instance to a physical network without the use of another piece of software named “IOUlive”Chetan Kumarhttp://www.blogger.com/profile/14148723201460363548noreply@blogger.com1tag:blogger.com,1999:blog-1915247286303611326.post-61286416401763927612011-05-07T14:55:00.000+05:302011-05-07T15:17:14.954+05:30Cisco IOU -- Part 2<span class="Apple-style-span" style="font-family: Arial, Helvetica, sans-serif;">Cisco IOU has been cracked by http://evilrouters.net & you can refer the http://evilrouters.net for more detail.</span><div><span class="Apple-style-span" style="font-family: Arial, Helvetica, sans-serif;"><br />
</span></div><div><span class="Apple-style-span" style="font-family: Arial, Helvetica, sans-serif;">Here i will introduce you with Cisco IOU which will help you for your CCIE R&S Exam.</span></div><div><span class="Apple-style-span" style="font-family: Arial, Helvetica, sans-serif;"><br />
</span></div><div><span class="Apple-style-span" style="font-family: Arial, Helvetica, sans-serif;">Over the internet you will get different version of Cisco IOU but all IOU are same as the original one , The difference is the topology.</span></div><div><span class="Apple-style-span" style="font-family: Arial, Helvetica, sans-serif;"><br />
</span></div><div><span class="Apple-style-span" style="font-family: Arial, Helvetica, sans-serif;">You can modify the topology by editing the NETMAP file . NETMAP file is the same file that we use in GNS. ( Please see How to Create NETMAP in other post ) </span></div><div><span class="Apple-style-span" style="font-family: Arial, Helvetica, sans-serif;"> </span></div><div><span class="Apple-style-span" style="font-family: Arial, Helvetica, sans-serif;">In IOU you can get Linux Base IOS, Below are the file name of Cisco IOS </span></div><div><span class="Apple-style-span" style="font-family: Arial, Helvetica, sans-serif;"><br />
</span></div><div><span class="Apple-style-span" style="font-family: Arial, Helvetica, sans-serif;">1] i86bi_linux-adventerprisek9-ms</span></div><div><span class="Apple-style-span" style="font-family: Arial, Helvetica, sans-serif;">2] i86bi_linux-adventerprisek9-ms</span></div><div><span class="Apple-style-span" style="font-family: Arial, Helvetica, sans-serif;"><br />
</span></div><div><span class="Apple-style-span" style="font-family: Arial, Helvetica, sans-serif;">In advance enterprise IOS you will get all feature that you get in Cisco 7200 series router with K9 image ot Adv IP Base IOS.</span></div><div><span class="Apple-style-span" style="font-family: Arial, Helvetica, sans-serif;"><br />
</span></div><div><span class="Apple-style-span" style="font-family: Arial, Helvetica, sans-serif;">Using GNS is good but when you what to run 20 or 30 router then it will create problem.</span></div><div><span class="Apple-style-span" style="font-family: Arial, Helvetica, sans-serif;">GNS is a emulator that emulate the hardware with original IOS so it require more CPU.</span></div><div><span class="Apple-style-span" style="font-family: Arial, Helvetica, sans-serif;"><br />
</span></div><div><span class="Apple-style-span" style="font-family: Arial, Helvetica, sans-serif;">If you want to run 20+ router in GNS then it will kill your CPU. So now you can go with Cisco IOU .</span></div><div><span class="Apple-style-span" style="font-family: Arial, Helvetica, sans-serif;"><br />
</span></div><div><span class="Apple-style-span" style="font-family: Arial, Helvetica, sans-serif;">In Cisco IOU you can 50+ routers or may more.( Req RAM not CPU )</span></div><div><span class="Apple-style-span" style="font-family: Arial, Helvetica, sans-serif;"><br />

</div><br />
<br />
From the Cisco Engineering Education web site (a long time ago):<br />
<blockquote>IOS on Unix (IOU) is a fully working version of IOS that runs as a user mode UNIX (Solaris) process. IOU is built as a native Solaris image and run just like any other program. IOU supports all platform independent protocols and features.</blockquote><br />
<h2><span class="Apple-style-span" style="font-family: Georgia, 'Times New Roman', serif; font-size: large;">What operating systems does IOU run on?</span></h2>It is my understanding that, initially, IOU was Solaris (SPARC) only. Nowadays, however, there are also builds for OS X and Linux. Similar to dynamips, IOU allows you to build out a network topology on a computer, without the need for physical routers. This is useful for validating designs, proof-of-concept testing, and certification self-study.<br />
<br />
<br />
<br />
<h1><u><span class="Apple-style-span" style="font-family: Georgia, 'Times New Roman', serif; font-size: large;">Warnings</span></u></h1><h2>Is this legal?</h2>Usage of IOU outside of Cisco (and trusted partners) is a potentially legal gray area. From an old internal-only Cisco web page:<br />
<blockquote>Cisco IOS on Unix is a tool intended for internal use only. Distribution of IOU images to customers or external persons, or discussion of IOU with customers or external persons, is prohibited. Don’t do it or we’ll have to come and kill you.</blockquote>Chetan Kumarhttp://www.blogger.com/profile/14148723201460363548noreply@blogger.com2tag:blogger.com,1999:blog-1915247286303611326.post-3398013818909568022011-03-15T16:53:00.002+05:302011-03-15T17:01:05.929+05:30EVC: Ethernet Virtual Circuits – Part 2<div>As we saw the basic of EVC in my earlier post <a href="http://chetanress.blogspot.com/2011/03/ethernet-virtual-circuits-evc-support.html">EVC: Ethernet Virtual Circuits – Part 1</a> & here we will dig some more to know about EVC.</div><br />
<div></div>1] What is Ethernet Flow point (EPF)? : - EPF is a Service Instance which classifies frames <br />
belongs to particular Ethernet service & also defines & applies feature,behavior & forwarding action. <br />
<br />
2] Ethernet Virtual Circuit (EVC): - EVC is management plane containers which represents <br />
globally & also do 1-toMany mapping for EVC to EPF.<br />
<br />
3] Bridge Domain (BD): - BD is a broadcast domain local to that device.<br />
<br />
<div></div><u><strong>EVC Bridge Domain: EVC bridges decouple VLAN from broadcast domain</strong></u>. <br />
<ul><li>VLAN are treated as encapsulation on a wire.</li>
<li>VLAN on a wire are mapped to internal bridge domain.</li>
<li>Result : Per – Port VLAN Significance.</li>
</ul><br />
<strong><u><span style="font-size: large;">Flexible Service Mapping </span></u></strong><br />
<ul><li>Service Instance construct Layer 2 Flow on Ethernet Interface </li>
<li>Single Tagged </li>
<li>Double Tagged </li>
<li>Header / Payload</li>
</ul><u><strong>Service Instance Mapping is specified by following command</strong></u> : <br />
<br />
<div></div><em><u>Encap do1q 100</u></em> : match any frame with Outer Tag equal to 100<br />
<br />
<div><em><u>Encap dot1q 100 sec 200</u></em> : match any frame with outer tag as 100 and second tag as 200</div><br />
<div><em><u>Encap Default</u></em> : Service Instance with default encapsulation matches all frame otherwise unmatched by any other S-I on the same port.</div><br />
<div></div><strong><u>Advance Frame Manipulation or VLAN Tag Manipulation </u></strong><br />
<ul><li>PUSH Operation : Add one VLAN Tag or Two VLAN Tag </li>
<li>POP Operation : Remove One VLAN Tag or Two VLAN Tag</li>
<li>Translation Operation : </li>
</ul> 1:1 VLAN Translation <br />
1:2 VLAN Translation<br />
2:1 VLAN Translation<br />
2:2 VLAN Translation<br />
<br />
The Biggest advantage on EVC is to support multiple services per physical port . That means you can have multiple service under one physical port.<br />
<ul><li>Local Connect </li>
<li>EoMPLS ( xconnect)</li>
<li>L2 Multipoint Bridge</li>
<li>L2 Multipoint Bridge ( VPLS , SVI-Based EoMPLS)</li>
<li>L2 Point to multipoint bridge </li>
<li>L3 Termination </li>
</ul><br />

<br />
Here is the brief of PUSH , POP & SWAP : <br />
<br />
1] PUSH : Adding a Lable to Incomming Packet and also aka Lable imposition <br />
2] SWAP : Replace the lable of incomming packet<br />
3] POP : Remove the lable from outgoing packet and also aka Lable disposition.Chetan Kumarhttp://www.blogger.com/profile/14148723201460363548noreply@blogger.com2tag:blogger.com,1999:blog-1915247286303611326.post-41722353628734474412010-12-18T01:21:00.004+05:302010-12-18T01:49:02.957+05:30Intermediate System - Intermediate System -- Part 1<span style="font-family: Calibri; mso-ansi-language: EN-US; mso-bidi-font-family: Arial; mso-bidi-language: AR-SA; mso-fareast-font-family: 'Times New Roman'; mso-fareast-language: EN-US;">ISIS</span><span style="font-family: Calibri; mso-ansi-language: EN-US; mso-bidi-font-family: Arial; mso-bidi-language: AR-SA; mso-fareast-font-family: 'Times New Roman'; mso-fareast-language: EN-US;"> was originally designed for Open System Interconnect (OSI) protocol Suite.
