Module Summary
 A distance vector routing algorithm sends its entire routing table
to its neighbors. Link-state routing algorithms maintain a complex
database of topology information, which routers use to maintain
full awareness of distant routers.
 OSPF is a classless, link-state routing protocol that is widely
deployed in many networks. EIGRP is a classless routing
protocol that behaves like a classful routing protocol by default.
 VLSMs allow multiple levels of subnetworked IP addresses within
a single network and provide efficient allocation of IP addresses.
