[isp-bgp] Expert assistance please

["Dennis Ott" <dott@...>]

I could use a little expert assistance with my BGP config.

I have 3 connections( 2 T1's, 1 5Mb ) with 3 ISP's.  I would like to route
all or nearly all of my outbound traffic through the 5Mb connection. But in
the event the 5Mb connection fails the other 2 T1's will continue to provide
connectivity.

I am of the understanding this can be accomplished with a weight, however
with my lack of experience with BGP I have not had complete success.

I would appreciate any advice with my config (snippet below).
