we have multiple VRF on an ASR and the snmp traps should be sent on different VRFs. All VRF has a dedicated Loopback interface which should be used as snmp trap source.

The snmp-server trap-source INTERFACE command can only be used for one interface. Is there any other way to do this? Maybe SNMPv3 supports it?

  • Are you trying to send certain traps to one destination, and other traps to another, Or, do you want all traps to go to multiple destinations?

  • I would like to send all traps to different destinations (with different source and VRF).

1 Answer 1


If you can find an IP address that's unique to all VRFs, you can place the source in its own VRF, then leak (or import) routes from the destinations in other VRFs.
