VPLS Configuration

VPLS Configuration : The Future

VPLS allows multiple Ethernet LANs from different customer sites to be connected together across the service
provider (SP) network, thereby emulating a single Ethernet LAN segment for that customer.

SP network providing VPLS services in which multiple customer sites (belonging to Customer A) can communicate
as if they are connected as a private Ethernet LAN segment. VPLS uses Multiprotocol Label Switching (MPLS) to
offer multipoint Ethernet connectivity over a mesh of logical circuits or tunnels, with the added benefits of Traffic
Engineering (TE), resilience, and failover. VPLS enables carriers and SPs to offer managed Ethernet VPN services
easily and cost effectively


  1. Hi Chetar, how would be the configuration on a CE ? Please I need My SP is configuring the PE's router and I have to configure my CE end router. But I don´t know how to do that.

  2. Hi LC,

    It depend on your PE Config. As you can see PE config is done in various flavor like Bridge Domain , Dot1q , QnQ.

    If ISP allow only once vlan then on CE side config normal switch port access or if your are else config with dotq1 which allow only single vlan.

    PE Can be configured with below option :-

    1] dot1q-tunnel Mode
    2] Trunk Mode
    3] access

  3. what switches do support this feature?
