Hi,


does anybody know if there is a show command that displays all the prefixes in the BGP table that match a specific extended community route target?


Thanks in advance

Hi,


There is a little trick: you define an extended community list specifying the RT and then use it with your show command, f.e.:


Router(config)#ip extcommunity-list standard CheckRT permit rt 65535:1

Router(config)#end

Router# show bgp vpnv4 unicast [all|rd|vrf] community-list CheckRT


Depending on your IOS version, the command syntax might vary slightly, but the ? is your friend ;-)

You can also use regular expressions within extended community lists. For the complete usage please check
