[j-nsp] Out-of-band on J-series

[Phil Mayers]

So,

On our M7i we use the 100meg management port to connect into our OOB
network. This network is a physically separate, flat addressed private
IP /16.

On the J-series, one does not have an fxp0 with the associated
protection from accidentally switching packets. What do other people do?
Use a routing instance with a spare port as the member? What
disadvantages does that give you (can you syslog into a routing
instance? ntp? snmp trap?)
