I'm in the process of setting up a redundant internet connection with two ISPs. I have two routers, each one connected to an ISP. Each router only has two interfaces. Is this going to work well? I'm thinking that there might be a bunch of issues with this configuration.
I'm wondering if it would be a better solution to
-add an additional interface to each router
-connect each router to each ISP
-use hrsp to failover
Comments or ideas?
