Unlike FR where IPs are actually assigned to the interfaces, in PPPoE configuration they are assigned to the Virtual-Templates. Virtual-Templates are not interfaces, so you cannot ping them.
Using unnumbered interfaces is the only way to provide self-ping in PPPoE setup, as far as I'm aware of. -- Marko Milivojevic - CCIE #18427 (SP R&S) Senior CCIE Instructor - IPexpert On Mon, Jan 30, 2012 at 04:50, George Leslie <[email protected]> wrote: > > > > > Hi all,Quick question.
