BGP configuration task list
On a basic BGP network, perform the following configuration tasks:
• Enable BGP.
• Configure BGP peers or peer groups. If you configure a BGP setting at both the peer group and
the peer level, the most recent configuration takes effect on the peer.
• Control BGP route generation.
To control BGP route distribution and path selection, you must perform additional configuration
tasks.
To configure BGP, perform the following tasks (IPv4 unicast/IPv4 multicast):
Configuring basic BGP:
• (Required.) Enabling BGP
• (Required.) Perform one of the following tasks:
ï‚¡ Configuring a BGP peer
ï‚¡ Configuring dynamic BGP peers
ï‚¡ Configuring a BGP peer group
• (Optional.) Specifying the source address of TCP connections
As a best practice,
configure BGP peer
groups on large scale
BGP networks for easy
configuration and
maintenance.
