Local switching IOS XR - Different Subinterfaces of Same Port?

[rcolohan]

On an ASR9000 is it possible to configure L2VPN local switching using two separate sub-interfaces that are configured under the same main physical interface? i.e.:

l2vpn
xconnect group TEST
p2p test-P2P
interface TenGigE0/1/0/0.100
interface TenGigE0/1/0/0.200
!

I know that "The interfaces can be on the same line card, or on two different line cards" but just have not seen it stated that my solution above would work.

Thanks

Hi

Yeah that will work. Just make sure that you pop tag on interface configuration

Something like this:

interface TenGigE0/1/0/0.100 l2transport
encapsulation dot1q 100
rewrite ingress tag pop 1 symmetric
!
interface TenGigE0/1/0/0.200 l2transport
encapsulation dot1q 200
rewrite ingress tag pop 1 symmetric
!
