Release Information
Statement introduced in Junos OS Release 12.3X50-D30 for the QFX Series.
Description
Enable a reverse-path forwarding check on unicast traffic (except ECMP packets) on all ingress interfaces.
Default
Unicast RPF is disabled on all interfaces.
Options
mode loose | — | The switch checks to see if the incoming packet’s source address is in the switch’s routing table, but the switch does not verify whether it would use the ingress interface to send a packet to the incoming packet’s source address. If the source address is in the routing table, the switch accepts the packet and forwards it as required. If you do not use loose mode, the switch checks to see if a packet is received on the interface that the switch would use if it were sending a packet to the incoming packet’s source address. If the packet fails this test, the switch discards it. This is called strict mode. |
