Hello,
I had setup a static route in a complex network to influence the path it would take. I decided to use the loopback address of the destination router (which is 2-3 hops away), not the next hop. It was by complete accident that I did this (but seemed logical to me at the time) - I was at a customer site and was completely burned out on the project. It worked, but on my way home I started to think about what I did and questioned how this even worked.
I also wanted to add that they are using an IGP, so there is full reachability throughout the WAN. Now, from all my studies and everything I read, the only two ways this is supposed to work is by pointing your destination prefix and prefix mask to the "next-hop" or "exit interface"
I am guessing it worked because it couldn't validate the loopback address. I am curious if anyone has more insight as to why it worked, and if I am going to experience any unforseen issues with this configuration in the future.
thanks,
-Brian
