Configuring BGP Basic Functions

This section does not differentiate between BGP and MP-BGP.

Prerequisites

The neighboring nodes are accessible to each other at the network layer.

Creating a BGP Connection

A router ID is the unique identifier of a BGP router in an AS.
To ensure the uniqueness of a router ID and enhance network reliability, 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. For information about global
router ID, refer to IP Routing Overview in the IP Routing Volume.
If the global router ID is used and then it is removed, the system will select a new router ID.
If the router ID is specified in BGP view, using the undo router-id command can make the system
select a new router ID.
