Configuring BGP basic functions

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.
