And not only that. Each ISP has it's own applications, requirement, and traffic patterns. Deploying various IGP might add values. --Ehab

on one protocol (if it ever will), their needs should be met.

If we do see pressure for convergence, it will be evidence that we've lost our hold on the multi-tier model. If we like the multi-tier model (and so far it's been useful) then we want to continue to make the IGP you run in a given domain a local matter. If it weren't we never would have seen OSPF or ISIS deployed widely in the first place.
