Redistributing Default Routes

By default, the redistribute command does not permit a default route to be redistributed into BGP. You can use the default-information originate command to override this behavior and permit the redistribution of default routes into BGP.

default-information originate

• Use to enable the redistribution of default routes into BGP.
• Use the route-map keyword to specify outbound route maps to apply to the default route. The route map can modify the attributes of the default route.
• This command takes effect immediately. However, if the contents of the route map specified with this command change, the new route map may or may not take effect immediately. If the disable-dynamic-redistribute command has been configured, you must issue the clear ip bgp redistribution command to apply the changed route map.
• Outbound policy configured for the neighbor (using the neighbor route-map out command) is applied to default routes that are advertised because of the default-information originate command.
• Policy specified by a route map with the default-information originate command is applied at the same time as the policy for redistributed routes, before any outbound policy for peers.
• Example

  host1(config)#router bgp 100

  host1(config-router)#default-information originate

• Use the no version to restore the default, preventing the redistribution of default routes.
• See default-information originate.
