Default Configuration There is no default BGP router ID. The system does not select a router ID automatically. One must be configured manually. Command Mode BGP Router Configuration mode User Guidelines The BGP router ID must be a valid IPv4 unicast address, but is not required to be an address assigned to the router. The router ID is specified in the dotted notation of an IPv4 address. Changing the router ID disables and reenables BGP, causing all adjacencies to be re-established. BGP is enabled by default once the administrator has specified the local AS number with the router bgp command and configured a router ID with the bgp router-id command. BGP is not operable until a BGP router ID has been assigned. The BGP administrative state (as set by the enable command) has no operational effect until a router id is assigned to the BGP router.
