as long as you've got 

 snmp {

you can use "<routing-instance>@<community>" as community when querying
a specific routing-instance.  E.g.

  snmpwalk -v2c -c voice at public myrouter ifName

to get a list of interface names in the "voice" routing-instance of
"myrouter" using the "public" community.
