L2VPN Xconnect

Wesoley

Hello gurus,

I have been trying to establish an L2VPN between two PEs. The xconnect comes up but I'm trying to find a way to ping the IPv6 address on the remote end from the RTR-EXT. I recognize that I can't used the BVI under the Xconnect but can do it under the bridge domain. Any ideas on how this can be accomplished?

hi wesley,

if the address on the RTR-EXT is locally configured, then you likely want to use a PWHE interface.

(pseudowire headend).

you'd apply your ip config directly on that virtual interface.

in your current example, you are switching the pw out of the interface 0/2/1/8. to terminate and route it locally, you can use the pwhe.

config sample:

generic-interface-list pwhe

interface Bundle-Ether100 << linkset between R01/RTR-EXT

!

interface PW-Ether60

mtu 1518

attach generic-interface-list pwhe

!

l2vpn

pw-class mpls

  encapsulation mpls

   control-word

  !

!

xconnect group pwhe

  p2p pwhe

   interface PW-Ether60

   neighbor ipv4 8.8.8.8 pw-id 60

    pw-class mpls

   !

cheers!
