Statement introduced before Junos OS Release 7.4.

Statement introduced in Junos OS Release 15.1F6 for PTX Series routers with third-generations FPCs installed.

Description

Check whether the packet has a source address with a corresponding prefix in the routing table. If a corresponding prefix is not found, unicast reverse path forwarding (RPF) loose mode does not accept the packet.

Default

If you do not include this statement, unicast RPF is in strict mode.
