the goal is simply to get a router address for a given interface.
i have a list of interfaces. some have ip addresses. some don't.
for those that do, i need the gateway address that they are
connected to.
But the point is that not every interface will have a router or
gateway on it. Some will, others may not. Even if there is a router
prepared to handle a certain type of traffic, your local
configuration might have been configured to not use it, and handle
traffic through a different one. Possible reasons for this are load
balancing and network redundancy.
So there might be a router on each interface, and then again possibly
not. There doesn't even HAVE to be a default gateway, as I can attest
from having borking a configuration. In this situation you can
connect only to machines local on the same net. Not very useful for
what we mostly want to do, yet it's still a "valid" configuration.
