IPv4 Routing Protocol

* Static Routing

* RIPv2

* EIGRP

* OSPF

* BGP

* Policy Routing

* IP Tunneling

IP Routing Overview

* Longest match routing

                - Most bits in common when finding the routing path

* Metric vs Administrative Distance

                - Same protocol vs different protocol

                - If different protocol, then it will compare with the Administrative Distance

                - If same protocol, then it will compare with the metric / hops /cost
