It's my understanding that the "area range" command on an ABR is for summarizin
g OSPF routes from any area going into area 0 only. It has no use outside of OS
PF. However, the address summary command is meant to be used on an ASBR to su
mmarize routes coming FROM non-OSPF protocols although sometimes people use it
to summarize routes going TO other protocols. -Mike

Right, that is what I did, R1 is a member of 2 areas, area 1 and area 0
.
Here is a partial output of "show ip ospf". This is why I don't unders
tand
why it isn't working. I thought that as long as the router was an ABR,
you
could use area range to summarize and inject into IGRP.
r1#sh ip os
Routing Process "ospf 100" with ID 141.63.10.1 and Domain ID 0.0.0.100
Supports only single TOS(TOS0) routes
Supports opaque LSA
It is an area border and autonomous system boundary router

Guy,
Although router1 is certainly an ASBR, it really doesn't become an ABR
until
it becomes a member of two or more OSPF areas. If you hung another
OSPF-speaking router off of router1 and placed it in an area different
from
router5, you would then see the results of your 'area range' command on
that
new router, because that new router would know how to read the type 3
summary LSAs being originated by router1.
