Configuring BGP basic functions
NOTE:
•
This section does not differentiate between BGP and MP-BGP.
• Since BGP employs TCP, you must specify IP addresses of peers, which may not be neighboring routers.
• Using logical links can also establish BGP peer relationships.
• In general, IP addresses of loopback interfaces are used to improve stability of BGP connections.
Configuration 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.
• 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.
To create a BGP connection:
