Honestly, I wouldn't use network statements and simply tag everything through static or connected redistribution and communities. Allows you more flexibility later and requires little more understanding up front but you'll be better off down the road.
something like router bgp abcd no sync redis static static-bgp redid connected connected-bgp ip prefix-list our-cidr seq 5 permit a.b.c.d/19 ip prefix-list internal-only seq 5 perm a.b.c.d/19 ge 20 route-map connected perm 10 match ip addr pref our-cidr set community as:115 route-map connected perm 20 match ip addr pref internal-only set community as:113 then on your exports you use route-maps that just match on community 115 or match on what other communities you have to tag other kinds of traffic.

Google has much info, but each leave thing out other use, no simple for dummies and cisco site scare me <330.gif> Thanks for help, much appreciate!

Route maps and communities could be a little overkill for what you are maybe trying to do. Also, the global routing table is almost 7 times bigger now than it was in 1998, so make sure you have enough memory. There are lots of calculators out there to determine appropriate memory requirements based on the expected number of received prefixes. -- Sent from my mobile device On 2011-10-29, at 5:29 AM, Edward avanti <[email protected]<mailto:[email protected]>> wrote: > Halo All, > > Could someone please advise if the configuring BGP guide from > http://www.cyberflunk.com/~nikm/cisco/bgp.html is still applicable for > today? > The article was wrote on 1998 for 4200, we have 7200 and before I kill our > company off face of planet into void I ask advise on if it still simple > advise for operation in 2011. > > Many regards > Edwardo > _______________________________________________ > cisco-nsp mailing list > [email protected]<mailto:[email protected]> > https://puck.nether.net/mailman/listinfo/cisco-nsp > archive at http://puck.nether.net/pipermail/cisco-nsp/ <ATT00001.c> _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
