Delete a Dynamically Learned Route

About this task

Delete a dynamically learned route from the routing table if you do not want the switch to use the route. Exercise caution when you delete entries from the routing table.

Procedure

  1. Enter Global Configuration mode:

    enable

    configure terminal

  2. View IP route information:

    show ip route [<A.B.C.D>] [-s default|-s <A.B.C.D/X>] [alternative] [count-summary] [spbm-nh-as-mac][preference] [vrf WORD<1-16>] [vrfids WORD<0-512>] [static]

  3. Delete the dynamically learned route:

    no ip route <A.B.C.D A.B.C.D | A.B.C.D/X> <A.B.C.D> dynamic

Example

Delete a dynamically learned route:

Switch:1>enable
Switch:1#configure terminal
Switch:1(config)#no ip route 192.0.2.32 255.255.255.0 198.51.100.31 dynamic
