Thanks for the response. Do you have the link for this?
How does the router determine if it has the best route? Does routing
protocol choice have anything to do with this determination? Using RIP for
example, the router only knows how many hops away a network is. It knows the
best route to forward the packet, but doesn't know if there is another
router with a better route that would have received the packet.

Under proxy ARP, if the router receives an ARP Request for a host that is
not on the same network as the ARP Request sender, and if the router has the
best route to that host, then the router sends an ARP Reply packet giving
its own local data link address. The host that sent the ARP Request then
sends its packets to the router, which forwards them to the intended host.
Scott,
That is quoted from the CCO help pages. Essentially, both of your scenarios
are true, except that the router only responds to the ARP if it has the BEST
path to the host or service sought.
