Hello all,
Just starting to get into my first networking job (have CCNA but no real experience). My company uses IS-IS and one of the first things I noticed was that someone seems to have tried to setup a loopback interface for management but its not working.
I have no intention of messing with anything config wise - I just have a question...from a quick read about IS-IS I understood that it didnt support virtual interfaces as it runs on layer 2 but then in IS-IS config guides I see them talking about setting up a loopback lo0
So....does IS-IS support virtual interfaces? If not then how does it support a loopback? Is a loopback not truly "virtual" in the sense that others are?
Thanks,
