Clearing Routes in the Unicast RIB

You can clear one or more routes from the unicast RIB.
The * keyword is severely disruptive to routing.
Caution
To clear one or more entries in the unicast RIB, use the following commands in any mode:
Command
clear {ip | ipv4 | ipv6} route {* |
{ route | prefix/length }[ next-hop
interface ]} [vrf vrf-name ]
Example:
switch(config)# clear ip route
10.2.2.2
clear routing [multicast | unicast]
[ip | ipv4 | ipv6] {* | { route |
prefix/length }[ next-hop interface ]}
[vrf vrf-name ]
Example:
switch(config)# clear routing ip
10.2.2.2

Verifying the Unicast RIB and FIB

To verify the unicast RIB and FIB information, use the following commands:
Command
show forwarding adjacency
show forwarding distribution {clients |
fib-state}
show forwarding interfaces module slot
show forwarding {ip | ipv4 | ipv6} route
