we are getting a backup internet connection through a different carrier. I would like to load balance between the two... i would like to purchase a cisco router to do this. Will a 2811 support this? I dont really want to buy a really expensive router. What is the smallest I would need? also, would it be better to use just a default route for each isp or do i need full \ partial routing tables? What is the benefit of full \ partial if we are just hosting a couple websites?
