BGP Operational Commands

BGP Show Commands

The BGP show commands provide detailed information about the BGP protocol operation and BGP routes.

BGP Summary

This command displays BGP protocol parameters like attributes or timers that are generic to the BGP instance.

Syntax:

show bgp summary <option>

Option Description

-

Without any option, the commands displays the information for all instances.
