BGP configuration task list
In a basic BGP network, you only need to perform the following configurations:
• 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):
Tasks at a glance Remarks
Configuring basic BGP:
• (Required.) Enabling BGP
•
(Required.) Perform one of the following tasks:
{ Configuring a BGP peer
{ Configuring dynamic BGP peers
{ Configuring a BGP peer group
• (Optional.) Specifying the source address of TCP connections

Generating BGP routes (perform at least one of the following tasks):
• Injecting a local network
• Redistributing IGP routes

(Optional.) Controlling route distribution and reception:
• Configuring BGP route summarization
• Advertising optimal routes in the IP routing table
• Advertising a default route to a peer or peer group
• Limiting routes received from a peer or peer group
• Configuring BGP route filteri
ng policies
