I think there is no such functionality in Cisco nor Juniper. If I turn 
out to be wrong, please let me and this list know.

Possible workarounds:

  - "central services" vrf with your management station. This is the 
standard workaround, and can be used for ping and ssh as well. Also 
called "common services", for a complete googling experience.

  - A GRE tunnel from your management station to the nearest core router 
for each VRF (Linux can do that, don't know about windows). If the core 
router is in the same rack, a VLAN trunk is simpler.

Again, if you come out with an SNMP proxy in a single box (not a 
distributed NMS with agents) that really supports VRFs (even with 
overlapping addresses) please let me know.

Hope this helps,
