Xconnect issue on BNG PW-Ether interface

[WonderBoy1990]

Hi,

I have encountered an issue which is for me is unusual. As seen on the diagram below (example only), I have router with sub-interface Gi0/0/0/0.30 which is connected to BNG1 and BNG2 via pseudo-wire. The problem is even if I have already configured BNG2 as backup neighbor, status of xconnect is down instead of standby. What could be the possible issue?

See sample config:

R
l2vpn
xconnect group VLAN30
interface Gi0/0/0/0.30
p2p neighbor 192.168.2.1 pw-id 30
backup neighbor 192.168.2.2 pw-id 30

===========

BNG1

l2vpn
xconnect group VLAN30
interface PE30
p2p neighbor 192.168.1.1 pw-id 30

===========

BNG2
l2vpn
xconnect group VLAN30
interface PE30
p2p neighbor 192.168.1.1 pw-id 30

==============

Appreciate your help.

we can check "show l2vpn xconnect detail" it will usually tell us a reason why the psuedowire is down.

Thanks

I tried the command but there was no error message. Usually an error message appears like for example if there is an MTU mismatch.
