morning

I need some help with this problem

I want to build a network consisting of a ring of routers that use OSPF to interconnect them.
Now one of those routers hooks to the gateway router that connects to the net, how do i tell the OSPf network how to connect to the internet and still retain its redundancy (one the the routers goes down in the ring)

*current network is a line with 0.0.0.0/0 pointing each tower to the down the line until end, this needs to change*

On the router which connects to the internet: It will broadcast a default route to the other OSPF routers as long as it also has a default route in its own routing table.

and this would be a 0.0.0.0/0 point to say 192.168.100.1, and this would be sitting in the ip routes table, correct?

Correct.

thank you
