Usage
Information
If you apply a route map to a BGP peer or neighbor with the neighbor default-originate
command configured, the software does not apply the set filters in the route map to that BGP peer
or neighbor.
When you configure a route-map for a BGP peer or peer group with the neighbor default-
originate command, the command checks for the existence of the route in BGP RIB.
Route-map configuration on a BGP peer or peer group works only when the LOC-RIB contains at least
one route.
When you apply a default route to a BGP peer or peer group using the neighbor default-
originate command, changes to the configured default route-map are applied to the BGP peer or
peer group only after a delay of 15 seconds. As a result, you must wait for a period of 15 seconds before
manually resetting BGP using the clear ip bgp command.
In case of eBGP, the neighbor default-originate command does not support extended-
community as a non-transtive route-map attribute.
