I have a location that we don't want anyone to accidentally route to. We run BGP as the only routing protocol along with some statics. The attached picture is what I currently have, but this is causing a problem. The router on the right side of the page connects to a switch that reloads itself occassionally. When it does this, it brings that link, from the left router to the right router, down. I want to know if I'm able to run a routing protocol between just those two routers, and will keep BGP from propagating that information out to my other locations. If I run EIGRP for just those two networks, can I keep BGP from propagating that learned route? Basically, I want to have the same functionality that I have with a static route now, but I don't want anyone else being able to see it other than my data center. I've thought about ACLs, and this may be the only way I can do it.
