[j-nsp] Logical routers and VRRP behaviour

[Gordon Smith]

Thanks Patrick,

That's exactly what I needed.
The scenario is half the primary logicals on one router, and the other
half of the primarys on the second router (lets me split load during
normal operation while still providing redundancy). 
Unfortunately, the JUNOS interface docs weren't very clear regarding
vrrp behaviour.

Since both routers have gig-e pics in them, I've got them split up into
tagged sub-interfaces for the logicals. Be nice to have more routers,
but.....  :-)

Cheers,
Gordon
