I'm in the process of setting up redundant Internet connections through two ISP's for my company, and need to know how I can configure my edge routers (running EBGP and OSPF) to advertise diverse routes respecitively used by the ISP's to connect to the Internet. These routes would in turn be redistributed into OSPF as default routes when they are available. If either of the routes become unavailable, then they would be removed from the OSPF routing table.
Can someone please help me by telling me how to configure my routers to accomplish this task?
Thanks,
