How about this, how do you see this scenario:

1) Client gets a DGID from 'someplace'
2) Client sends a SA query to resolve the DGID to a Path Record
3) Client configures a QP based on the Path Record

Now, the question I'm interested in is this:
During step #3 what test should the client apply to determine if a GRH should be used with the QP.

This is the scenario that I need to resolve.

What would happen if the GRH flag were always set? Set only if the GID prefixes of the SGID/DGID were different?
