Yes this sounds like something I might try, Right now I have 8 routers.
4 routers connected to a frame relay full mesh then off that four more
routers on a local VLAN segment. One router behind each of the Routers
connected to the WAN, each group of two routers is there own Area, with
the WAN betweem them all being a separate Area and Im just trying
different ways to do things in OSPF. SO right now Im working on
advertising loopbacks I know there are a few ways to change the mask on
a loopback when its advertised into OSPF, network type, summarization,
and redistribution. Im pretty fluent with a lot of the network type and
redistribution, but summarization and filtering with funky subnet masks
is something of a weak point right now Im trying to shake. So Im going
through excersies. But in the end result I wanted to have one router
that has a loopback advertised without the host address and everyone
else to receive that host address. I can remember that eigrp has a leak
map and BGP has the unsuppress map just trying to figure out what OSPF
has that's similar. But in this case more similar to the unsuppress map.

It also depends what the topology looks like. If the summarization is
internal on an abr you could filter it out to other areas with an lsa-3
filter (area filter-list).
