Enabling unicast Reverse Path Forwarding
Unicast Reverse Path Forwarding can be enabled in dierent modes.
The strict mode is enabled when you enable uRPF on ICX 6610 devices. The prexes learned over the VE interfaces that do not have
tunnel-termination specied as a next hop are enabled. On ICX 7750 devices, the uRPF check enables the interface level CLI and
hardware settings. You should reload the device after enabling reverse path check for this conguration to be captured in the system
settings.
NOTE
Refer to the FastIron Command Reference for a complete list of supported commands.
1. Enter global conguration mode.
2. Enter the reverse-path-check command.
The following example enables uRPF at the global level.
device(config)# reverse-path-check
Conguring unicast Reverse Path Forwarding modes
Congure the various unicast reverse path forwarding modes on a layer 3 VE or physical interface.
You must enable unicast reverse path forwarding globally before you enable the required forwarding modes.
1. Enter interface conguration mode.
2. Enter the rpf-mode command followed by the required mode (strict or loose) you want to congure on the device. You can
optionally use the exclude default route (urpf-exclude-default) check on the physical interface.
