- EIGRP is inserted in dynamic routing category, where the best route calculated by the number of routers in the past, or bandwith route calculation. WIGRP routing configuration enough to register the network address that is connected directly with the wildcard mask and will be in exchange routing tables to neighbors to update / introduce network address.
- The Software that i use is cisco packet tracer v.5.3
