[j-nsp] mixed interface, switching + routed

[Josh Reynolds]

Hello,

I'm sure this is a fairly basic question, but I'm having trouble
finding a solution.

I have a port that is currently an ethernet switching port, set in
access mode that is tagging a vlan for upstream. This works fine. What
I'd like to do, is add a sub interface on the master port (say, unit
600 / vlan 600) that is a tagged/routed interface.

I've tried to do this a couple of ways now, and every time I seem to
get thrown a different error.

Anybody have any tips?

Thanks :)
