For IBGP to work the ASN for both routers have to be the same, also turn off
synchronisation - unless you are running an IGP with full connectivity. How
do you intend to use both links - active/backup, or active/active?

Greetings,

I have a couple of 7140 that we are connecting to ATT and Time Warner via a
couple of T3 circuits.  I have never configured BGP before but for better or
worse it fell on me to do it.  

The ATT circuit wont be in for a couple more days but everything seems to be
working just fine over the time warner circuit using the following bgp
config.

Since I am somewhat of a novice, I thought I would put what I came up with
out to this group for comment and criticism.  

BTW -I am using confederation because I could not get ibgp to work...

The main requirement right now is ISP redundancy...  there wont be a great
deal of growth at this site in term of additional ISPs...  We may upgrade
the T3 to OC3 at some point but that is a long way off.

Appreciate comments.... thanks
