Syntax
bgp router-id router-id
no bgp router-id
• router-id—An IPv4 address in dotted quad notation. This is the address for
BGP to use as it’s router ID.
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 re-
enables 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.
