I have a 7513 router with two seperate T1 connections to two seperate providers. Running BGP with full routes to both. During peak periods one connection runs at 100% capacity constantly while the other runs at 20% max capacity. My upstream providers tell me nothing other than static routing takes a priority over BGP. However, no matter what I route statically it makes no difference at all. Static routes just have not effect. Can anyone point me in the right direction to balance my load out??
In what direction are you hitting 100%. If this is inbound you need to look at what you can do to make the lower utilised path more attractive. If you have just one prefix to announce you're pretty stuck but its not necessarily impossible. In this case you could look to see if your upstream providers support communities to prepend your announcements upstream this may have some effect, making the heavily loaded circuit less preferred when its announced to other providers - who them may select the other ISP's route to you. If you have more than one prefix you could prepend your AS on the heavily loaded link to make it less attactive thus moving reply traffic (inbound) to the other ISP. Its possible you could split your announcement into two and then make half preferred via one ISP and half preferred by the other.
If the load is high outbound you need to adjust the local preference for some of the routes learned from the less loaded ISP. This will make these routes better and move the outbound traffic to that path.
All load balancing in BGP is tricky, from the above I'd assume its the inbound traffic thats the problem.
You need to make small changes and observe the effect, otherwise you'll just move all the traffic and gain nothing.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
