The AS number in EIGRP is really more of a routing participation group identifier. All routers with the same ID will participate in EIGRP. It has no real relation to the Autonomous System used in BGP and for good reason. BGP is an exterior routing protocol. As such, you have a group of ASes that must interact in the Internet and they must have unique identifiers.
Such is not the case with EIGRP. Your instance of EIGRP within your network will probably never interact directly with the instance of EIGRP running in a different network. Even if you wanted to do this, both networks could add an additional instance of EIGRP using a different ID. I hope that makes sense. As usual, it's early and I think my explainer is broken.

Like BGP, I am not sure if they have private and public range of AS that can be applied to EIGRP? If so, what's the range for private AS for EIGRP? Who assigns the public AS range? Thanks All!
