User Guidelines
This command overrides for a specific routing interface the fast external
fallover behavior configured globally. If permit is specified, the feature is
enabled on the interface, regardless of the global configuration. If deny is
specify, the feature is disabled on the interface, regardless of the global
configuration. The command no ip bgp fast-external-fallover clears the
interface settings and indicates that the global settings should be used.
Example
console(config-if-vlan1)#ip bgp fast-external-fallover permit
ip community-list
Use this command to create or configure a BGP community list. To delete a
community list, use the no form of this command.
