ASR1001 BDI configuration equivalent to BVI's and bridge-groups in IOS?

[andrew.butterworth]

I have been asked what the equivalent of bridge-groups and BVIs is for an ASR1001 and I am struggling to find an example.

If we have this IOS configuration:

bridge 1 protocol ieee

bridge 1 route ip

!

interface GigabitEthernet0/1

bridge-group 1

!

interface GigabitEthernet0/2

bridge-group 1

!

interface BVI 1

ip address 10.10.10.10 255.255.255.224

!

What would be the equivalent for an ASR1001 with IOS XE?

Thanks

Andy

interface Gig0/1
   service instance 1 ethernet
     encapsulation untagged
     bridge-domain 1
interface Gig0/2
   service instance 1 ethernet
     encapsulation untagged
     bridge-domain 1
interface BDI1
   ip address x.x.x.x

Thanks for the quick reply Edison.  I searched for a good half hour trying to find this...

Are there any performance penalties with configuring this as opposed to applying the IP address to a physical interface (its for resilience and needs to be connected to a failover pair of ASA's via a stack of 3750's).

Cheers

No performance penalty but you are extending your L2 domain which comes with other caveats (i.e. broadcast storms, etc).

Hi Edison,

With BDI how is spanning-tree done?
