Drops traffic when the null 0 statement becomes the active setting as determined by the route-hop selection process for IPv4 policy-based routing.
Route-map configuration mode
If none of the configured next-hops or interfaces are up, this command drops the traffic.
The no form of this command removes the configuration.
The following example configures the next hop as NULL0 interface, dropping the packet instead of forwarding it.
device(config)# route-map test-route permit 99 device(config-route-map-test-route/permit/99)# set ip interface null0
