Cisco Nuts,

Here is what I did in the lab:  I entered a class c loopback address on a
router with a /32 mask.  We'll call that router b.  I had both OSPF and
EIGRP running with all of the defaults on routers b and router a.  With a
/24 network statement under both EIGRP and OSPF on router b, I had just the
EIGRP route in the table of router a.  Adding a /32 network statement under
the router b OSPF config results in two entries in the router a table - the
/24 EIGRP route and the /32 OSPF route.  I then disabled EIGRP autosummary
on router b.  Now router a has no OSPF routes in the table.  What does all
of that prove?   That administrative distance always wins the war - but only
where the masks are equal.  A more specific mask is a whole different network.

Again, I think the appearance of the /32 OSPF routes in your tables of your
routers has to do with how OSPF handles p-t-mp NBMA circuits (that
"additional" information must include /32 addresses of neighbors).

As for your table of router b, I would check to see that EIGRP autosummary
is disabled on all routers and also verify that the appropriate network
statements with the appropriate masks are in place.
