The following example shows how to begin a new epoch and increment the epoch number of all Cisco Express Forwarding tables for the IPv6 address family:
Router# clear cef table ipv6 vrf *
The following example shows the output before and after you clear the epoch table and increment the epoch number. Before clearing:
Router# show ip cef epoch
Table: Default-table
Database epoch: 3 (43 entries at this epoch)
After clearing:
Router# clear cef table ipv4
Router# show ip cef epoch
Table: Default-table
Database epoch: 4 (43 entries at this epoch)
The following examples shows how to clear Cisco Express Forwarding tables for all VRF tables in the IPv4 address family. This examples shows sample output with Cisco Express Forwarding debugging (debug cefcommand) enabled:
Router# clear cef table ipv4 vrf *
