Context: Use these commands to monitor BGP operation and verify configuration status.

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.

    Example:

    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
