Right, but the bottom line is that "connected" and/or "static"
routes don't become known to ospf until they're redistributed
into ospf. Routes may heard over the interface once an adjacency
is established, but in this case neither router is feeding any
routes into ospf, so there's nothing to pass.
Other routes may exsit in the environment beyond what are explictly
in the configuration, PPP negotation may inject a /32 for the peer
address, OSPF may create internal routes (this isn't clear) to
adjacent neighbors.
And the usuaul reminder with OPSF, add a loopback to the configuration
for OSPF to pick up as the router-id or specifiy a router ID so that
OSPF does not pick one at random.
