So at my new job, our network has a single point of failure that we have only one connection at our data center to the wan cloud connecting all our remote locations. We want to install a second link in case of failures. I was told start thinking of ways to make the routing work. The goal is the main link is used exclusively, and the backup which has a lot less bandwidth is used only if the main link fails.
Currently the existing link terminates to a router we have that learns the wan routes via bgp and redistributes them into ospf as Type 1 Externals.
Is this as easy as terminating the new circuit to another router, and redistributing the same routes as Type 2 externals?
It seems almost too simple and easy so now I’m second guessing.
Ospf domain is flat Area 0.
