Usage Guideline DXS-3600 Series 10GbE Layer 2/3 Switch CLI Reference Guide The command is used to configure multiple adjacent Autonomous Systems in a confederation. The Autonomous Systems, specified in this command, are visible internally to the confederation. Each Autonomous System is fully meshed within itself or configures a route reflector. Use the no bgp confederation peers command to delete all the or part of the AS numbers, configured earlier. Use the show ip bgp confederation command to verify your settings. Example In the following example, Autonomous Systems 21, 22, 23, 24, and 25 are configured to belong to a single confederation using the identifier 10.
