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.
