6.4.5 Applying an edited configuration

When you change a configuration, it takes effect as soon as you enter the configuration command. If you have edited the BGP filter settings, however, you must instead execute the clear ip bgp operation command to apply the changes to the switch operation.

On execution of the clear ip bgp operation command, changes made to the configuration by the following commands take effect automatically:

• access-list command

• prefix-list command

• route-map command

• distribute-list in command

• distribute-list out command

• redistribute command

• neighbor in command

• neighbor out command

A command input example is shown below.

(config)# ip access-list standard 1  .............................(1)
(config-std-nacl)# permit 10.0.0.0 0.255.255.255  ................(2)
