Hi Chris,

If you don't mind, I'd like to ask a similar question whose answers
might be instructive for the question you asked:

Forgetting all of the theoretical constructs for a moment, has anyone
here personally encountered an operational scenario in which ICMP
redirects solved a problem for you that you would otherwise have found
difficult or intransigent? Without naming names, would you describe
the scenario's details, explain the problem that would have existed
absent redirects and explain how redirects solved it for you?
