[c-nsp] Need some help troubleshooting l2tpv3 tunnel

[Steven Pfister]

I see... didn't notice that before. If I assign an address to a subinterface of f0/0 on the local side and point the remote side of the tunnel to that, what address should I use? Something from the vlan in question?

And while I'm at it, I'll try and move the f0/0 on the remote side to a new subinterface (not f0/0.77)

I know I should really use loopback interfaces in setting this up, but this is a very temporary solution to try and ease the deployment of some new servers to about a dozen remote sites. I was hoping to get away with something quick 'n' dirty.

Thanks!

It looks like you have the incorrect ip address on the remote site or the
tunnel xconnect pointing to the wrong interface on the local side (FE2/0
instead of FE0/0)
