5000 Series Layer 2/3 Managed Data Center Switch CLI Reference Guide 11-51 neighbor default-originate (BGP Router Config) To configure BGP to originate a default route to a specific neighbor, use the neighbor default-originate command in BGP router configuration mode. Use the optional if-default-present parameter to originate the default route to a specific neighbor only if the default route exists in the routing table. By default, a neighbor-specific default has no MED and the Origin is IGP. Attributes may be set using an optional route map. A neighbor configured with the default-originate is placed in a separate update group from the neighbors that are not configured with this command which means the global default-originate command does not affect the neighbors configured with this command. The global default-originate command is overridden by the default-originate setting for a neighbor if enabled. The AS-PATH sent in the default route update sent to the neighbor as a result of this command includes only the originator's AS. Giving the optional if-default-present tells to originate the default route to this neighbor only if the default route is present in the routing table. This form of default origination does not install a default route in the Adj RIB Out for the update group of peers so configured (it will not appear in show ip bgp neighbor advertised-routes). A route map may be configured to set attributes on the default route sent to the neighbor. If the route map includes a match ip-address term, that term is ignored. If the route map includes match community or match as-path terms, the default route is not advertised. If there is no route map with the route map name given, the default route is not advertised. Use the no command to prevent BGP from originating a default route to a specific neighbor. neighbor ip-address default-originate [if-default-present] [route-map map-name] no neighbor ip-address default-originate [if-default-present] [route-map map-name] Parameters ip-address if-default-present route-map map-name The neighbor's IPv4 address. (Optional) Use to route the originate default route to a specific neighbor only when the default route exists in the routing table. (Optional) A route map may be configured to set attributes on the default route advertised to the neighbor. Default The default is No Default originated. Command Mode BGP Router Config 11-52 neighbor default-originate (IPv4 VRF Address Family Config) To configure BGP to originate a default route to a specific neighbor, use the neighbor default-originate command in IPv4 VRF Address Family Config mode. Use the optional if-default-present parameter to originate the default route to a specific neighbor only if the default route exists in the routing table. By default, a neighbor-specific default has no MED and the Origin is IGP. Attributes may be set using an optional route map. A neighbor configured with the default-originate is placed in a separate update group from the neighbors that are not configured with this command which means the global default-originate 1057
