I'm trying to get my head around the exact operation of VPLS configuration on PE routers whereby, according to the MPLS Fundamentals Guide, to add a CE facing port to a given VFI instance you should use an SVI as follows:
hostname VPLS-PE-1
!
mpls label protocol ldp
mpls ldp router-id Loopback0 force
!
l2 vfi cust-one manual
vpn id 1
neighbor 10.100.100.2 encapsulation mpls
neighbor 10.100.100.3 encapsulation mpls
!
interface FastEthernet4/2
no ip address
switchport
switchport access vlan 111
spanning-tree bpdufilter enable
!
interface POS5/1
ip address 10.10.1.1 255.255.255.0
mpls ip
mls qos trust dscp
!
interface Vlan111
no ip address
xconnect vfi cust-one
But is there any reason why this has to be an SVI interface? I am about to lab this but thought I would pose the question, to make sure I am on the right track... is there any reason why I can't do this for Fa4/2 and just forget about using VLAN 111 and its SVI?
interface FastEthernet4/2
no ip address
xconnect vfi cust-one

Hello Steven,
we have just deployed a network for a customer where we used the l2vpn vfi new syntax on ME-3600-X.
We have still a command that connects the SVI to the VFI but it has become member vfi
modern syntax on ME-3600-X:
mpls label protocol ldp
l2vpn
logging pseudowire status
router-id 192.168.246.25
!
l2vpn vfi context COMPLESSO-CAVALLI-GEOSCENZE
vpn id 100100101
autodiscovery bgp signaling ldp
vpls-id 65001:100100101
rd 65001:100100101
route-target export 65001:100100101
route-target import 65001:100100101
!
interface GigabitEthernet0/1
description *** COMPLESSO CAVALLI - GEOSCENZE ***
switchport trunk allowed vlan none
switchport mode trunk
service instance 10 ethernet
encapsulation default
l2protocol forward
service-policy input SetDSCP
!
!
+
bridge-domain 101
member GigabitEthernet0/1 service-instance 10
!
+
interface Vlan101
no ip address
member vfi COMPLESSO-CAVALLI-GEOSCENZE
!
As you see there is still the need to link the VPLS l2vpn vfi object to the SVI.
So I don't think you will be successful with your tests.
Hope to help
Giuseppe
