Guides users through Border Gateway Protocol configuration processes and provides practical examples for implementation and ongoing network maintenance.
Border Gateway Protocol
Describes the Border Gateway Protocol used for interdomain routing in the Internet.
Default BGP configuration
Lists the default BGP configuration settings for the router. This information helps administrators understand the baseline state of BGP features before applying custom network policies.
Enable BGP routing
Configure BGP routing to enable dynamic routing protocol functionality on your network device.
Managing routing policy changes
Configure BGP routing policy changes by checking route refresh capability and resetting BGP sessions.
Configure BGP decision attributes
Configure BGP decision attributes to control path selection behavior and routing decisions in your BGP network.
Configure BGP filtering with route maps
Configure BGP filtering using route maps to control next-hop processing for inbound and outbound routes.
Configure BGP filtering by neighbor
Configure BGP filtering by neighbor to control routing updates using access lists or route maps.
Configure BGP filtering by access lists and neighbors
Configure BGP filtering by specifying access list filters on incoming and outgoing updates based on BGP autonomous system paths.
Configure prefix lists for BGP filtering
Configure prefix lists to control BGP route filtering by specifying permitted or denied network prefixes.
Configure BGP community filtering
Configure BGP community filtering to control which BGP communities are sent to neighbors and to filter community attributes.
Configure BGP neighbors and peer groups
Configure BGP neighbor and peer group settings by applying router configuration commands to specific IP addresses or peer group names.
Configure aggregate addresses in a routing table
Configure aggregate addresses in BGP routing tables to summarize route advertisements and control path information.
Configure routing domain confederations
Configure BGP routing domain confederations by specifying a confederation identifier and autonomous system peers.
Configure BGP route reflectors
Configure BGP route reflectors to improve scalability by reducing the number of required iBGP peering sessions in your network.
Configure route dampening
Configure BGP route dampening to reduce the impact of route flapping on network stability.
Conditionally inject BGP routes
Configure conditional injection of more specific BGP routes into a routing table to provide finer granularity of traffic engineering or administrative control.
Configuring peer session templates
Describes how to create and configure peer session templates using specific configuration tasks to streamline BGP neighbor configurations.
Configure a basic peer session template
Configure a basic peer session template with general BGP routing session commands that can be applied to many neighbors.
Configure peer session template inheritance with the inherit peer-session command
Configure peer session template inheritance with the inherit peer-session command.
Configure peer session template inheritance with the neighbor inherit peer-session command
Configure a device to send a peer session template to a neighbor to inherit the configuration from the specified peer session template with the neighbor inherit peer-session command.
Configuring peer policy templates
Provides sample output for the show ip BGP injected-paths command used in conditional BGP route injection configuration.
Configure basic peer policy templates
Configure basic peer policy templates with BGP policy configuration commands that can be applied to many neighbors.
Configure peer policy template inheritance with the inherit peer-policy command
Configure peer policy template inheritance using the inherit peer-policy command to create a peer policy template that inherits configuration from another template.
Configure peer policy template inheritance with the neighbor inherit peer-policy command
Configure peer policy template inheritance with the neighbor inherit peer-policy command.
Monitor and maintain BGP
Lists privileged EXEC commands for clearing and displaying BGP routing tables, caches, and databases.
