BGP Regular expressions / Public route-servers

I was looking at some older posts at Groupstudy and Dale  posted the link to public route-servers. I agree the best way to practice regular-expressions for CCIE is to use one of the following public route-servers.

From: http://www.cymru.com/Documents/secure-bgp-template.html

 route-views.oregon-ix.net
 ner-routes.bbnplanet.net
 route-server.cerf.net
 route-server.ip.att.net
 route-server.east.attcanada.com
 route-server.west.attcanada.com
 route-server.cbbtier3.att.net
 route-server.gblx.net
 route-server.as5388.net
 route-server.savvis.net
 route-server.colt.net
 route-server.opentransit.net
 route-server.gt.ca
 public-route-server.is.co.za (South African routes only)
 route-server.belwue.de
 route-views.on.bb.telus.com
 route-views.ab.bb.telus.com
 route-server.ip.tiscali.net
 route-server.wcg.net
 route-server.manilaix.net.ph
 route-server.ip.ndsoftware.net
 route-server.utah.rep.net
 route-server.he.net
 zebra.swinog.ch

Just telnet to one of the above route-servers and you can login via guest/anonymous account. There you go and you can use some basic show commands.
