Use the neighbor remove-private-AS command to remove private AS number from the AS_PATH of BGP route. This section describes the neighbor remove-private-AS command.

Adjusting the Administrative Distance of BGP routes allows BGP routes to be preferred over routes by other routing processes. This section describes how to adjust the administrative distance for BGP routes.

Route dumping is the feature that reduces the impact of BGP route flap. This section explains how BGP route dampening works and the configuration commands in Cisco IOS.

BGP applies triggered updates that send routes when there is some kind of change. The minimum advertisement interval slightly delays the advertisement of BGP routes when changes occur.
This section describes the commands for configuring the minimum advertisement interval for BGP routes.

BGP neighbors are basically maintained by exchanging KEEPALIVE messages periodically; this section describes the timer settings related to KEEPALIVE messages.

This is an example of BGP route filter configuration with route-map. Route-maps allow you to flexibly identify BGP routes to filter by referencing standard/extended ACLs, prefix-lists, and AS_PATH ACLs in the match condition.

This section describes the configuration and verification commands for BGP route filtering using route-map. The route map allows you to identify BGP routes to filter by reference to standard/extended ACLs, prefix lists, AS_PATH ACLs, etc. In addition to filters, additional path attributes can be set for BGP routes.

This is an example of BGP route filter configuration by filter list (AS_PATH ACL). It is important to know how to represent the AS_PATH attribute in a regular expression.
