I'm doing this now between ASR920's, works fine. Here's an example of what I'm doing:
ASR-920-1 interface GigabitEthernet0/0/22 description xxxxxxxxxx mtu 9000 no ip address load-interval 30 carrier-delay msec 0 negotiation auto ! service instance 3936 ethernet description xxxxxxxxxxxxxxxxxxxxxx encapsulation dot1q 3936 rewrite ingress tag pop 1 symmetric xconnect x.x.x.x 3936 encapsulation mpls (loopback IP of ASR2) mtu 1600 ! ASR-920-2 interface GigabitEthernet0/0/13 description xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx mtu 9000 no ip address load-interval 30 carrier-delay msec 0 negotiation auto cdp enable ! service instance 3936 ethernet description xxxxxxxxxxxxxxxxxxxx encapsulation dot1q 3936 rewrite ingress tag pop 1 symmetric xconnect x.x.x.x 3936 encapsulation mpls (loopback IP of ASR1) mtu 1600 !
