Description: The cExtSnmpTargetVrfTable extends the snmpTargetAddrTable of the SNMP-TARGET-MIB for providing:

- VRF reachability criterion for the SNMP target - VRF filtering criterion for the SNMP target

This table is indexed by the target entity snmpTargetAddrName and the associated VRF name cExtSnmpTargetVrfName. Each entry of this table forms a tuple of target and VRF name for which all the VRF related configuration parameters can be specified by corresponding instances of the columnar objects.

The reachability of the SNMP target is qualified by the routing context by way of associating VRF Name(s) with it. Restricting only those SNMP notifications that are generated within the context of a VRF to a specific SNMP target is VRF based filtering of notifications.

A row in this table cannot be created prior to the creation of row it extends.
