Hi,
We recently installed AWS Direct Connect which was successful but now we are looking at the best way to automatically fail over if our Direct Connect fails to route via our back VPN.
The setup
Cisco 6500 distributes routes via OSPF internally to all production environments with one area set.
A second Cisco 2901 was installed to support the AWS Direct Connect which uses BGP with a single ASN. This router is connected to the Cisco 6500 and now within the OSPF area. Static routes exist to the Cisco 2901 currently which unless we physically detach from the network fail over wont work.
What we want to achieve
The Cisco 2901 Direct Connect to be the default AWS route until we have a link issue or alike and dynamically fail over to our VPN via the firewall to AWS. What we are confused is do we advertise these BGP routes within OSPF or should we setup BGP on the Cisco 6500?
I appreciate your time.
