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

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?
