Re: [nsp] Routing between VLANs using 802.1q

You do know that you create sub-interfaces and that the encap goes
on the sub-interface, not the main one? It's not obvious until
you've been there.

It definitely works on 12.0.[78]S on PA-FE's, though be careful
about deleting sub-interfaces if you're using *CEF...
