Use this command to set the BGP router ID. There is no default BGP router ID. The system does not select a router ID automatically. You must configure one manually.
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 IP address. Setting the router ID to 0.0.0.0 disables BGP. Changing the router ID disables and re-enables BGP, causing all adjacencies to be re-established.
