EIGRP does not use ip default-network. You need to redistribute ospf into
eigrp or setup a static default route and redistribute it.

Subject: EIGRP default network problem
Scenario: r2 e0 <-> e0 R3, R3 s0 <-> s0 r4.
* R2 runs OSPF
* R3 is asbr running OSPF and eigrp. R3 redistributes eigrp to ospf. It
does not redistribute ospf into eigrp.
* R4 runs only eigrp
Problem: R4 cannot get to OSPF cloud or anywhere outside. 192.100.1.0 is
network redistributed into ospf from RIP. Note that 192.100.1.0 is in R3
routing table and also is marked as candidate for default with next hop to
R2 e0. I put in default network, but R3 will not pass this default to r4.
Before changing my lab routers to run eigrp instead of IGRP, it was working.
Here is my config. thank you for helping
