Enabling Unicast Reverse Path Forwarding

Unicast Reverse Path Forwarding can be enabled in different modes.
Both strict or loose modes can be configured when you globally enable uRPF on RUCKUS ICX devices. uRPF is not supported on tunnel interfaces. When uRPF is enabled on a VE interface or a physical interface with an IP address configured, the prefixes learned over these uRPF-enabled interfaces will be checked with the uRPF criteria. On RUCKUS ICX devices, the uRPF check enables the interface level CLI and hardware settings. You should reload the device after enabling reverse path check for this configuration to be captured in the system settings.
  1. Enter global configuration mode. 
    device# configure terminal
  2. Enter the reverse-path-check command. 
    device(config)# reverse-path-check

The following example enables uRPF at the global level. 

device# configure terminal
device(config)# reverse-path-check
