snmpwalk / ipRouteMask / VRF

STUART KENDRICK · ‎07-17-2008

hi,

i've virtualized my network using VRF-Lite ... and now i'm realizing that i don't know how to access parameters specific to a VRF. for example, an snmpwalk on ipRouteMask returns the Native VRFs route table ... but not the route table of any of the other VRFs. [that makes sense]

is there a mechanism for walking a table belonging to a VRF? i'm imagining something like community string indexing, for walking a table associated with a particular VLAN (e.g. 'snmpwalk -c public@100 testswitch dot1dTpFdbAddress', in order to dump the dot1dTpFdbAddress table for VLAN100)

Yes. See http://www.cisco.com/en/US/docs/ios/12_3t/12_3t2/feature/guide/gtsnmpvp.html . You will need to use SNMP contexts to gain access to the individual VRF instances. However, only certain MIBs are context-aware thus far.
