Ted - I think it's just as likely for the RG to get different
information from different interfaces (or different "administrative
domains") as it is for a host to get get different information
directly. Traffic from the host, which is then forwarded by the RG to
one of more than one possible interfaces or routers, might be affected
by the configuration information from the "administrative domain"
through which the traffic is forwarded.
Now, I admit I'm describing a hypothetical and abstract scenario. I
don't have a specific example of a situation in which a host might
make decisions - either in the stack or in an application or ??? -
about outbound traffic based on knowledge of how that traffic would be
forwarded by the RG.

How realistic is it anyway that an RG would get different *relevant*

an administrative error. Of course the broadcast address and
subnet mask options might be different, but it doesn't make sense to
send the RG, e.g., different name servers for each interface.
