I have a question regarding debalancing of the two equal uplinks within the same AS. I have two routers that have BGP established between them. Although we are couple of hundreds of miles away, we do belong to the same autonomous system.
We have established two redundant links, both 100Mbps of bandwidth. At the moment we have set up neighboring and we do have BGP balancing links almost perfectly - automatically splitting traffic in half. Now, what I want to do, is to debalance those links. Reason is that each link uses separate com. channels - first one is going via my main STM-1 link, later one is going through protection channel.
What I want is that my network prefers first link over the second one, but to automatically switch onto the second link in the case first one is experiencing delays, heavy traffic, or looses connectivity. I would like to use first (primary) link for about 80 or 90% of my traffic, and to use second(ary) link for the rest of the traffic, unless first link fails.
As far as I could've figure this out, I think I need to set EIGRP load balancing in order to do such thing (debalance two equal links, in ratio 90% - 10%) (link is here http://www.cisco.com/en/US/tech/tk365/technologies_tech_note09186a008009437d.shtml#topic1 )
Please do say if you have any better advice how to do such thing, I would really appreciate someone else's thoughts on this. Thank you in advance!
