PPPoE Server on CiscoASR 920

[ty.chan007]

Does Cisco ASR 920 support PPPoE server on either BDI or Phy interface? 

I tried to find refer DOC but no able to find where specifically mention support or not support.

I can configure  and client can connect but routing was not working. I also can not do show interface vi2.x .

Hello,

PPPoE server is NOT supported on BDI (check the link below). Also, the BDI or the VI used by the PPPoE client should not be used for routing.

What are you trying to accomplish ?

I am trying to enable PPPoE server on my router, ASR920. it can be Physical or BDI Interface.

As you mentioned, BDI does not support as PPPoE Server interface.

How about Physical interface ? like G0/0/0 or G0/0/1 ?
