In Acee's review of the info model, he asked about ECMP routing. Wikipedia defines ECMP as "Equal-cost multi-path routing (ECMP) is a routing strategy where next-hop packet forwarding to a single destination can occur over multiple "best paths" which tie for top place in routing metric calculations." I felt the info model could handle expressing ECMP simply by having multiple selected routes for the same destination prefix. But I wondered if this was a question that should be asked more broadly than just in the context of the info model. Juliusz once said on a babel thread "Of the multiple routes to a given destination, at most one is selected." Is this a necessary condition (due to the nature of Babel?) or is it simply that none of the implementations do ECMP? Barbara
