It is possible, but (as mentioned on the list) is useful
in rare situations. Where it can be useful however, is
where you have non-overlapping sets of neighbors for each
protocol instance, even though they all are reachable through
the same interface.

Something like this is possible with the unnumbered option
for p2p links. In this case you assign a single IP address
to the box and refer all p2p links to it. This address is
used as the src/dst address for packets locally originate/received.

If you're using UNIX, you could potentially write a pseudo-interface
driver and use it to simulate a network topology with multiple
processes, each representing a single router.
