Configuring Basic BGP4+ Functions

Basic BGP4+ functions must be configured before you configure subsequent BGP4 functions on a BGP4+ network.

Usage Scenario

Basic BGP4+ functions must be configured first when you configure BGP4+ for inter-AS communication.

Pre-configuration Tasks

Before configuring basic BGP4+ functions, configure link layer protocol parameters and IP addresses for interfaces to ensure that the link layer protocol on the interfaces is Up.

Starting a BGP Process: A BGP process must be started before configuring BGP functions. When starting a BGP process, specify the number of the AS to which the device belongs.

Configuring IPv6 Peers: Devices can exchange BGP4+ routing information only after the IPv6 peer relationship is established among them.

(Optional) Configuring the Local Interface for a BGP4+ Connection: When loopback interfaces are used to establish a BGP4+ connection between two peers, the local interface used for the BGP4+ connection needs to be configured on the devices.

Verifying the Basic BGP4+ Configuration: After configuring basic BGP4+ functions, verify BGP4+ peer information.
