Configuring basic BGP
This section describes the tasks required for a BGP network to work.
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, you can 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.
• If the global router ID is used and then the interface that owns the router ID is removed, the router
selects a new router ID.
• 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.

physical interface IP address as the router ID
regardless of the interface status.
