You can't summarize using the area range command to routers in the same
area. The trick to this is to put the lookbacks into a separate area and
then use the area range command.

Subject: OSPF: summarization of loopbacks - is it possible?
Hi!
I have x amount of loopback interfaces configured in
my internal router. I need to summarize them. Loopback
interfaces by default are host routes, workaround is
to enable "ip ospf net point-to-point" under their
local interface - and their actual subnet is
advertised.
That is fine.
But the problem is that loopback interfaces when they
are advertised using the network command ie - NOT
redistribute connected. Seem NOT to be able to be
summarized using the area range command. When I use
the redistribute connected and summary-address - this
works!!!
What is the problem here? Or is redistribute-connected
inclusive of summary-address the ONLY way to summarize
loopback networks?
rgds,
Sage
