Sorry for the late replies, I was too busy to try out the solution given...
I found the solution using the followings :
router1
router ospf 100
area 2 range 170.100.2.0 255.255.255.0
( 170.100.2.0 is actually /30 )
router2
roter ospf 100
area 1 range 170.100.1.0 255.255.255.0
( 170.100.1.0 is actually /32 (lookback address )
I summarize those non /24 routes into a /24 bit so that all the other OSPF
area get a standard /24 area and gets redistributed into IGRP...
I need to apply some distribute-list because of frame-relay sending the
routes back into IGRP with a lower administritive distance...
I tried to use the ip default-network command but it did not go into the
gateway of last resort for IGRP... how is this command use and when to use
it ???
I read about this in Caslow book page 356-367.
