In the previous post, we designed and implemented the foundational setup of our enterprise network. Now, we'll take a step further by configuring EIGRP (Enhanced Interior Gateway Routing Protocol) to dynamically manage routing between our three sites: London, Manchester, and Glasgow. This will eliminate the need for static
