[c-nsp] Route reflectors, BGP router redundancy et. Al.

[Ibrahim Abo Zaid]

Hi Chris

to complete this general discussion , i believe the other thing you need to
do to to determine and configure your BGP peering policy Main/Backup ISP ,
route advertised to each peer , recieved routes .

i believe the below link can be useful

http://www.cisco.com/warp/public/459/hsrp_bgp.html

but as Jay said , a network topology will be better .

best regards
