Bridge two subinterfaces on Cisco ASR

I have a Cisco ASR 1004 (RP2) running IOS-XE.

I am trying to bridge 2 sub interfaces into one L2 group so any traffic can flow between them just like they were switchports.

The interfaces currently look like this:

>interface GigabitEthernet0/1/2.2000
> encapsulation dot1Q 2000
>interface TenGigabitEthernet1/0/0.2000
> encapsulation dot1Q 2000

Is this possible, if someone could point me in the right direction for what to look for?

Thanks in advance
