Armand,
You cannot sumamrize routes in Area 0 under OSPF. You need to summarize
them as part of a different, non-backbone area. That should do it...
Regards,

Subject: OSPF into IGRP using Summarization solution
Hello,
This is a tough one to get working. I have three
routers one running IGRP the other two in OSPF. I have
searched the archives for solutions and still can't
get this one to work. Router 5 shows all area 1
networks /29 with help of "summary-address"
command. Router 5 does NOT see any Area 0 /27 routes
in routing table.I have tried the "area 0
range" command on R4 with no luck. Please look at
my configs and tell me what I'm missing here.
Any help would be appreciated.
