ASR920 sub interface

[mkouame17]

Dear Guys,

We just received a new ASR920 and I try to create a sub interface but I can't.

After some research I find that we have to use a bridge domain.

For test purpose I connect my laptop to the router in peer to peer mode.

And I create bridge domain (see configuration below),I try to ping from my PC to the ASR920 but it doesn't work.

interface GigabitEthernet0/0/0
 no ip address
 negotiation auto
 service instance 1 ethernet
  encapsulation dot1q 412
  bridge-domain 412
 !
interface BDI412
 ip address 10.70.12.1 255.255.255.0
end
!!!!!This is the show run of the router

Hi @mkouame17 ,

Hi @luis_cordova 

I already see this topic and as you can see it is the same config I apply here also.

I try to do router in sitck with this router.

interface GigabitEthernet0/0/1
 service instance 1 ethernet
  encapsulation dot1q 412
  bridge-domain 412
!
service instance 2 ethernet
  encapsulation dot1q 413
  bridge-domain 413
end


interface BDI412
ip address 10.70.12.1 255.255.255.0
no sh
exit
!
interface BDI413
ip address 10.70.13.1 255.255.255.0
no sh
exit

But it doesn't work. The interfaces are up but there is no connectivity.

Hi guy,

The issue was on the switch side. I used a new switch and it works fine.

Thanks
