The section describes BGP basic configuration.
n
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.
The neighboring nodes are accessible to each other at the network layer.
Follow these steps to configure BGP basic functions:
To do...
Enter system view
Enable BGP and enter BGP
view
Specify a Router ID
Specify the AS number of a
peer or a peer group
Configure a description for a
peer or a peer group
Enable IPv4 unicast address
family for all peers
Enable a peer
Ignore a peer or peer group
