Get some BGP regex practice

If you want to test your regular expression skills you can use the show ip bgp regex command .

But you dont have a router with a big enough bgp table. then use one of the number of route servers out on the internet like this one telnet://route-server.ip.tiscali.net/

Try this command show ip bgp regexp _174_ to see all the routes that have traversed AS 174 for example.
