Configuring basic BGP
This section describes the basic settings required for a BGP network to run.
Enabling BGP
A router ID is the unique identifier of a BGP router in an AS.
To ensure the uniqueness of a router ID and enhance availability, specify in BGP view the IP address
of a local loopback interface as the router ID.
If no router ID is specified in BGP view, the global router ID is used.
To modify a non-zero router ID of BGP, use the router-id command in BGP view, rather than the
router id command in system view.
If you specify a router ID in BGP view and then remove the interface that owns the router ID, the
router does not select a new router ID. To select a new router ID, use the undo router-id command
in BGP view.
