[c-nsp] load balance over two unequal cost links?

[christopher_a_kane at bankone.com]

That could be achieved with some metric manipulation depending upon the 
protocol/s you are running. I think the objective would be more load 
sharing than load balancing. But, before you go down that path, I'd be 
concerned about the percentage of traffic that is TCP based. Depending on 
distance and loads, could you incur out of sequence conditions that would 
lead to so many re-transmissions as to render the solution more of a 
hindrance than a help?

Got the following:

  A----------B
   \        /
    \      /
     \    /
      \  /
       C

Cisco 3640's.  T1's between sites. 

I'm looking for a way to load balance traffic from site A to site B
using the link between A <> B and A <> C <> B.  Can I split traffic
based upon a particular port on the A router and load balance it using
both paths to B from A?  Thanks.
