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):

Remarks
Configuring basic BGP:
• (Required.) Enabling BGP
• (Required.) Perform one of the following tasks:
{ Configuring a BGP peer
{ Configuring a BGP peer group
• (Optional.) Specifying the source interface for TCP connections
HP recommends that
you configure BGP peer
groups on large scale
BGP networks for easy
configuration and
maintenance.
Generating BGP routes (perform at least one of the following tasks):
• Injecting a local network
• Redistributing IGP routes
N/A
(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 filtering policies
• Configuring BGP route dampening
N/A
(Optional.) Controlling BGP path selection:
• Specifying a preferred value for routes received
• Configuring preferences for BGP routes
• Configuring the default local preference
• Configuring the MED attribute
• Configuring the NEXT_HOP attribute
• Configuring the AS_PATH attribute
