One issue that is being overlooked here is that what if your OSPF network
has a subnet that is using a 22-bit mask. You certainly can't summarize that
to 24 bits. The key is what was previously mentioned. You announce another
classful network using the ip default-network command. This should be
something other than 170.100.X.X. This should be a network in another area.
It could be a BGP route as long as the redistributing router has the route
in his table. I have this working in both 11.2.19 and 12.0.6.
r1 and r2 are neighbors over a frame connection
r2#
int lo0
ip add 140.10.10.1 255.255.255.0
!
router ospf 100
net 140.10.10.0 0.0.0.255 area 4
net x.x.x.x x.x.x.x are 0 [serial link]
r1#
router ospf 100
redist igrp 100 route-map red_igrp
network x.x.x.x x.x.x.x area 0 [serial link]
!
router igrp 100
redistribute connected
!
!
route-map red_igrp permit 10
match ip address 1
route-map red_igrp deny 20
!
!
ip default-network 140.10.0.0
!
access-list 1 permit [whatever networks you want to redistribute]
The 140.10.0.0 should show up in the IGRP routers table as a candidate
default route. Clear your route table a few times and it should work. It
will also work after reload.
Let me know if there are issues with this and I will post the rest of the
config.
There is another hokie method of working around this but is not recommended
and that is secondary addressing. Add a secondary address with the same bit
mask that you are trying to redistribute and it should work. Again, this is
not recommended.

Subject: OSPF into IGRP
Hi all,
Need some help here..
I am trying to redistribute OSPF into IGRP....
OSPF have some /24 /29 /30 routes whereas IGRP have only
/24 routes....
all of them are in 170.100.0.0 networks.
What are the command to redistribute all the subnets from OSPF into
IGRP..
How do I summarize those /29 and /30 routes into /24 routes in OSPF ??
Thanks
Stanley
