this thread kinda gets back to the point of core topics. OSPF like all
routing protocols, is a core topic. OSPF newbies should be trying things and
observing results. it's probably too much to expect folks to read the RFC,
but the Cisco design guide on CCO, as well as the various IOS configuration
guides offer a lot of information, including specifics about this
phenomenon.
the original question - how does one get rid of /32's - did not provide a
crucial piece of information - whether the /32's were loopback addresses or
NMBA interface addresses. the cures and resulting implications are different
for either.
BTW, NMBA is a core topic, and one should understand the implications to ANY
routing protocol over such a topology.
in the context of Lab preparation, one must be prepared for the possibility
that an evil lab scenario will require no /32's and forbid one from changing
of the NMBA cloud to a broadcast network. now what?
best wishes
Chuck

When you use ip os network point-to-multipoint on your frame relay interface
you also get a /32 throught the ospf system. You
can get rid of these by using ip os network broadcast instead.

MANAGER(config-if)#ip ospf netw ?
broadcast Specify OSPF broadcast multi-access network
non-broadcast Specify OSPF NBMA network
point-to-multipoint Specify OSPF point-to-multipoint network
point-to-point Specify OSPF point-to-point network
MANAGER(config-if)#ip ospf netw broad
OSPF: Invalid type for interface <<<<---------nope!!!!!
MANAGER(config-if)#
gotta check things, folks.

For loopback interfaces, network type "point-to-point" will fix it for
sure. I know that someone mentioned "broadcast" would do it also, but I'm
not sure about that since I haven't tried it.
I think that redistributing connected rather than advertising the interface
statically will also do it. Try it and let me know...

routes.
