I currently have 2 upstream's and only 1 router, planning to add a second router for redundancy, is it over kill (or even possible?) to get each upstream to allocate 2 ports on their router so that each of my routers will have 2 upsteams or is it more than sufficient to just do 1 upstream per router? It's extremely unlikely to have 1 upstream and one router fail at the same time, I think.
Does that make since?
