Hi ,
we have MPLS network running Layer3 VPN.
Presently in legacy network we have trunk between CS1 & Cs2 over transmission (ethernet link), Network diagram is attached herewith
We like to migrate the trunk over MPLS backbone. Can I connect the CS1 & CS2 to respective PE1 & PE2, after that the L2 VPN can carry the vlan traffic between CS1 & CS2 over L2 VPN.
Looking for the suggestion.
Reagrds,
Nilesh

Hello Nilesh,
what you would like to do is indeed possible: what you need is port based EoMPLS and this is supported in most PE nodes.
see
all you need is to use loopback IP addresses that are advertised over the MPLS cloud as LDP endpoints.
1. enable
2. configure terminal
3. interface gigabitethernetslot/interface
4. xconnect peer-router-id vcid encapsulation mpls
where peer-router-id is the other L2 PE loopback ip address.
Be aware that the L2 PE will not discriminate between vlan-ids so if there are vlan-ids that you don't want to propagate you need to use
switchport trunk allowed vlan on the L2 CE node.
Hope to help
