QinQ Bridging on ASR920

[rasmus.elmholt]

Hi

I have an ASR920 where I use 3 of the ports to terminate a QinQ connection. 2 of the ports I have equipment with QinQ support and the last is just a normal Dot1Q trunk to a firewall.

Can anyone verify that all broadcast packets received with a Tag of 3010:2 on te0/0/2 will be floded to both Te0/0/5 dot1Q and te 0/0/4 QinQ?

interface TenGigabitEthernet0/0/2
 mtu 9000 
 no ip address
 no negotiation auto      
 service instance 3010 ethernet
  description From ISP
  encapsulation dot1q 3010 second-dot1q 1-4094
  rewrite ingress tag pop 1 symmetric
  bridge-domain 3010

interface TenGigabitEthernet0/0/4
 mtu 9000 
 no ip address
 service instance 3010 ethernet

The configuration shown worked as expected. The problem was somewhere else.
