originate command.
Parameters

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.
You cannot set this configuration for a peer that is associated with a peer group. Similarly, you cannot associate a
peer to a peer group if that peer is already configured with these settings.
