I do have a problem on and ASR920. I configured two service instances on one physical interface for different .1q VLANs. Both instances attach the same device into the same bridge-domain. This is intended to be used for two euqal services from a single CPE. Every instance needs to rewrite the incoming VLAN-TAG.
interface GigabitEthernet0/0/3 service instance 34 ethernet encapsulation dot1q 34 rewrite ingress tag translate 1-to-1 dot1q 101 symmetric bridge-domain 4 split-horizon group 0 ! service instance 35 ethernet encapsulation dot1q 35 rewrite ingress tag translate 1-to-1 dot1q 102 symmetric bridge-domain 4 split-horizon group 0 !
The problem here is , that the BD seems to be "NOT VLAN-aware" and learns the MAC from both instances which results in a FlipFlop behaviour and packetloss for one of the instances.
Is it true that the ASR920 can not distinguish between the same MAC-Adr with differen .1q tags int the same bridge-domain.
