ok 3 routers:
corinth ---> sparta ---> athens ---> f0/0
all running eigrp
on the right side of athens is a network 10.1.1.0/24
this network shows up in corinth's routing table.
I use the following command on athens to mark the network as default:
ip default-network 10.0.0.0
I also advertise the network via eigrp.
yet corinth is not seeing it as the default route.
can you see why?
Here are my configs, I put descriptions on the interfaces.
