The current UnDP implementation does not provide support for VRF aware MIB's.
A good example of this is the NHRP MIB (refer http://www.cisco.com/en/US/docs/ios/sec_secure_connectivity/configuration/guide/sec_dmvpn_nhrp_mib.pdf)
In order to access the tables within this MIB for each VRF, multiple snmp contexts need to be defined, and the MIB OID actually contains value data. This can be seen in the below screen dump, where the displayed OID contains the NextHopInternetworkAddr.
This looks to be like a very poor Cisco 'hack' to support VRF's - but we have what we have....
Cool, got it and logged it into the system
