You can use any of these commands to display specific BGP information as needed:

Before you begin

None

Procedure

1.

Run the show bgp cidr-only command to display routes with non-natural network masks or Classless Inter-domain Routing (CIDR).

Example:

Router# show bgp cidr-only
2.

Run the show bgp community command to display routes that match a specific BGP community.

Example:

Router# show bgp community 1081:5 exact-match
3.

Run the show bgp regexp regular-expression command to display routes matching an AS path regular expression.

Router# show bgp regexp "^3 "
4.

Run the show bgp command to display all entries in the BGP routing table.

Example:

Router# show bgp
5.

Run the show bgp neighbors ip-address [ advertised-routes | dampened-routes | flap-statistics | performance-statistics | received prefix-filter | routes ] command to display neighbor information.

The following keywords display specific BGP neighbor information:

  • advertised-routes : all routes that the router advertised to the neighbor

  • dampened-routes : dampened routes learned from the neighbor

  • flap-statistics : flap statistics for routes learned from the neighbor

  • performance-statistics : performance statistics for the BGP process and this neighbor

  • received prefix-filter : the received prefix list filter

  • routes : routes learned from the neighbor

Example:

Router# show bgp neighbors 10.0.101.1
6.

Run the show bgp paths command to display all BGP paths in the database.

Example:

Router# show bgp paths
7.

Run the show bgp neighbor-group group-name configuration command to display the effective configuration for a neighbor group, including any configuration inherited by this neighbor group.

Example:

Router# show bgp neighbor-group group_1 configuration
8.

Run the show bgp summary command to display the summary status of all BGP connections.

Example:

Router# show bgp summary
