And how is CSV immuned from these same set of possible routing scenarioes?

Are you saying that once CSV authorizes a submission at the MSA, then there
is no need to further perform CSV during the route and only at the MDA?

What if you have this topology?

        MUA ---> MSA1/MTA1 -----> MTA2 ---->  MDA3

MSA1 and MDA3 is CVS ready.  MTA2 is not.

How does MDA3 handle this using CSV?  What is the policy here?
