Is this a possible setup?
Is it less reliable than having both routers from the same manufacturer?
Is it more difficult to get working that both routers from the same manufacturer?
My customer already has these 2 routers. I am able to do it easily with 2 draytek routers but I dont want to tell my customer to bin a cisco 800 for a draytek 2600. However my current cisco ios knowledge is limited to how to get into configure mode.
