Hello all,


We have an ASR1002 with

asr1000rp1-adventerprisek9.03.05.01.S.152-1.S1.bin

software.


I couldn't find any documentation on how to attach an L2 interface, in my case a subinterface with a single dot1q vlan, to a BDI interface.

I'm able to create a bridge-domain interface but it's down down.


The command bridge-domain on the subinterface

http://www.cisco.com/en/US/docs/ios/lanswitch/command/reference/lsw_b1.html#wp1042944 is an "Unrecognized/Invalid command"


Please point me in the correct doc to accomplish something seemingly so simple.


Thank you.

Hi


Here is one way to do it:

interface Gig0/0/2
   service instance 1 ethernet
     encapsulation dot1q <> second-dot1q <>
     bridge-domain 1
interface Gig0/0/3
   service instance 1 ethernet
     encapsulation dot1q<> second-dot1q <>
     bridge-domain 1
interface BDI1
   ip address x.x.x.x


http://www.cisco.com/en/US/docs/routers/asr1000/configuration/guide/chassis/bdi.html#wp1141221


Kindly note that bridging is supported from IOS XE release 3.2 and the features are somewhat limited in terms of bridging on ASR platforms.


Cheers

Sush

Sush,


Thanks for the response.


It works. I'll just have to look into the limitations of this type of setup.
