[j-nsp] ISIS Adjacency Problems

[Patrik Olsson]

Hi!

You need to add family iso to lo0.

Also you need to add all interface units to protocols isis.

Or do I misinterpret your config dump?

If I enable it for this new interface and disable IPv6 in the interface config in ISIS, I still see hellos going out with IPv6 capability.  Here's my config:
