[j-nsp] Multiple VLANs on single M7i FastE port

[Ben Dale]

I'm not sure if you're sanitising your config, but I don't think you'll be able to commit with a network address applied to an interface (eg: 10.0.1.0/24) - it'll have to be a host address.

I tried a configuration similar to the one below and connected it to a trunk port on an EX switch. Unfortunately, the subinterfaces can not communicate with other devices on that switch with the same vlan-ids.
