The Cisco CCO has a description on default n/w :
http://www.cisco.com/warp/customer/105/default.html
Since you are using a class B 170.10.0.0 for your topology, you can
redistribute the
ospf into IGRP. It all depends on how you configurae the OSPF, sinec
R2/R5 at area 0,
if R4/R5 at other area (eg 45), you can use area range to summaries /28
and /26 to two /24 and then redistribute into IGRP at R4.

Subject: default-network and igrp (classic flsm/vlsm)
Hello,
Here is the scenario:
R2 --- R5(E0) ---(E0) R4 (S0) --- (S1)R1
R4,R1 running igrp
R4- R5 - OSPF virtual link
R5-R2 - OSPF area 0
IGRP and OSPF mutually redistributed on R4. R1 (/24) don't see
R4 S1 170.10.15.1/24
R4 S0 170.10.15.1/24
R4 (e0) 170.10.11.65 / 26
R5 (e0) 170.10.11.66 / 26
R2 -- R5 Frame Relay network 170.10.10.32/28.
Classic FLSM/VLSM scenario. R1 (/24) don't see R2-R5 network .
One of few solutions (right?)- use ip classless (I have it on)
And use ip default-network.
I've put ip default-network 170.10.0.0 on R4
All it did - it created static route in running-config: ip route
170.10.0.0
255.255.0.0 170.10.10.0
It did not put any gateways of last resort on R4 or R1.
Can I use ip default-network to solve this problem?
And how.
