why do we advertise loopback in interface on router for EIGRP? It make sense to advertise routers network with EIGRP, but why loopback0?
1. could be needed to connect to router from remote location. loopback is always up up, never down. advertise it and u will be able to connect to router.
2. just to have some networks in home lab. i.e., to practice summarization, add 10-20 loopbacks and advertise them thruough network
