[j-nsp] (no subject)

Dear Mr. Cheeze (or should we call you Nacho?),

Chapter 9 of
http://www.juniper.net/techpubs/software/junos/junos82/swconfig82-net-mg
mt/download/swconfig82-net-mgmt.pdf (SNMP Support for Routing Instances)
is enlightening here.

 Specifically, you can query the MIB objects from a particular
routing-instance by including the name of your logical router in a
community string (for SNMPv1/2) - router_a at public would query a virtual
router called "router_a" with the community string "public".

 Specifically, the BGP MIB is a "Class 1" supported MIB for logical
routers, so JunOS claims full support for the MIB in logical routers.

Cheers,
