Hello, We need to terminate a lot of double tagged vlans on ASR1K devices (ASR1006/ESP20)to provide pppoe/dhcp connectivity. Currently we work with sub-interfaces but as it is difficult to manage and maintain thousands of sub-interfaces we are looking for a better way to implement this. In our case the outer vlan is ambiguous while the inner vlan defines the service.The problem is that normal sub-interfaces do not support ambiguous outer vlans. Using EVC, we can match ambiguous outer vlans but in order to map them to a layer3 interface (BDI interface) we need to pop the vlans, however "rewrite ingres tag pop 2 symmetric"is not supported on ambiguous vlans. Is there any way on the ASR1000 to match ambiguous outer vlans and to terminate them for pppoe/dhcp services without having to create thousands of sub-interfaces? Will ambiguous outer tag vlans be supported on normal sub-interfaces in a future release? Christian
