5.3 Configuring BGP Basic Functions

The section describes BGP basic configuration.
Note:
This section does not differentiate between BGP and MP-BGP.
Since BGP employs TCP, you need to 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.
5.3.1 Prerequisites
The neighboring nodes are accessible to each other at the network layer.
5.3.2 Configuration Procedure
