Forwarding Options
- Override default unicast RPF and FBF behavior (PTX10001-36MR,
PTX10002-36QDD, PTX10003, PTX10004, PTX10008, and PTX10016)—When unicast reverse-path
forwarding (unicast RPF) and filter-based forwarding (FBF) are configured on an interface,
the source IP address lookup of an incoming packet is done by unicast RPF in the routing
instance that the interface points to and destination IP address lookup is done in the
routing instance specified by the FBF filter. You use
set forwarding-options no-rpf-fbf-handling
to override this default behavior and revert to the old behavior where the source IP lookup happens in the routing instance specified by FBF.[See no-rpf-fbf-handling.]
