Is there any way to solve problem above?

The approach described in <http://www.nanog.org/mtg-0505/abley.cluster.html > would probably work, so long as the routers choosing between the ECMP routes are able to make route selections per flow, and not just per packet (e.g. "ip cef" on a cisco).


Tony Kapela did a lightning talk a few meetings ago about another cisco-specific approach which used some kind of SLA-measuring cisco feature to do the same thing without needing to run a routing protocol on a server. I can't seem to find a link to the details, but if someone else knows where it is it'd be good to know.
