Serial HDLC Sub Interfaces

Unanswered Question
Jun 9th, 2007

We have a DS3 point-to-point circuit and want to configure sub interfaces on this line while keeping the encapsilation HDLC. We're only able to pass traffic over the physical interface and not the sub-int. Is this possible or do we need to change to Frame Relay?

Thanks!

I have this problem too.

Hi,

No, you can't use HDLC with subinterfaces, only main interfaces, you must go for Frame Relay if you require subinterfaces.
