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	As a best practice, 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	N/A
(Optional.) Tuning and optimizing BGP networks: Configuring the keepalive interval and hold time Configuring the interval for sending updates for the same route Enabling BGP to establish an EBGP session over multiple hops Enabling immediate re-establishment of direct EBGP connections upon link failure Enabling 4-byte AS number suppression Enabling MD5 authentication for BGP peers Configuring BGP load balancing Configuring IPsec for IPv6 BGP Disabling BGP to establish a session to a peer or peer group Configuring GTSM for BGP Configuring BGP soft-reset Protecting an EBGP peer when memory usage reaches level 2 threshold	N/A
(Optional.) Configuring a large-scale BGP network: Configuring BGP community Configuring BGP route reflection Ignoring the ORIGINATOR_ID attribute Configuring a BGP confederation	N/A
(Optional.) Configuring BGP GR	N/A
(Optional.) Configuring BGP NSR
