| An understanding of the following key points should have been achieved: A router will not forward a packet without a route to a destination network. Network administrators manually configure static routes. Default routes are special static routes that provide routers with gateways of last resort. Static and default routes are configured using the ip route command. Static and default route configuration can be verified using the show ip route, ping, and traceroute commands. Verify and troubleshoot static and default routes Routing protocols Autonomous systems Purpose of routing protocols and autonomous systems The classes of routing protocols Distance vector routing protocol features and examples Link-state protocol features and examples Route determination Routing configuration Routing protocols (RIP, IGRP, OSPF, EIGRP, BGP) Autonomous systems and IGP versus EGP Distance vector routing Link-state routing
