Hi,
I have the scenario in the figure of the .pptx file attached.
I want to setup two pseudowires to transport Eth. tagged frames between CEs. I have an XR 12k platform with IOS XR 4.2.3. Here are the relevant configurations I made:
PE2-3
interface GigabitEthernet0/4/0/1
cdp
!
interface GigabitEthernet0/4/0/1.21 l2transport
dot1q vlan 21
!
interface GigabitEthernet0/4/0/1.22 l2transport
dot1q vlan 22
!
l2vpn
pw-class A21
encapsulation mpls
transport-mode vlan
tag-rewrite ingress vlan 21
!
!
pw-class A22
encapsulation mpls
transport-mode vlan
tag-rewrite ingress vlan 22
!
!
xconnect group PROVA
p2p VLAN21
interface GigabitEthernet0/4/0/1.21
neighbor 192.168.0.13 pw-id 11
pw-class A21
!
!
p2p VLAN12
interface GigabitEthernet0/4/0/1.22
neighbor 192.168.0.13 pw-id 12
pw-class A22
!

***************************************
As you can see from the "show" above, pseudowires stay up. Unfortunately ping from CEx to CEy do not work. For instance, if on CE1-1 I execute "ping 10.1.13.1", the ping does not work. What I found out is that the first Ethernet frame, which is an ARP request, arrives at PE2-3, but does not keep on going to CE2-1. Surely there is a problem with VLAN tags.
Does anybody have an idea on how to let things work ? The same setup with routers using IOS works fine.
Thanks a lot in advance.
