<p>Static routing is a process where routes are manually added to the routing table. Configuration involves specifying the IP addresses and interfaces on routers, as seen in the example with routers R1, R2, and R3.</p> Signup and view all the answers

<p>The main advantages of static routing include no routing overhead for the router CPU and added security since only administrators can permit routing to specific networks.</p> Signup and view all the answers

<p>In large networks, static routing can be tedious as administrators must manually add each route, and new administrators may require extensive knowledge of the network topology.</p> Signup and view all the answers

<p>Distance vector routing protocols determine the best path based on distance and direction, where routers share their routing tables with direct neighbors. An example includes RIP (Routing Information Protocol).</p> Signup and view all the answers

<p>Link state routing protocols maintain a complete view of the network topology by flooding link state information, unlike distance vector protocols that rely on neighbors' data.</p> Signup and view all the answers

<p>Knowledge of network topology is crucial for static routing because administrators must manually configure each route accurately based on the network structure.</p> Signup and view all the answers

<p>Router R1 has IP address 172.16.10.6/30 on s0/0/1 and 192.168.20.1/24 on fa0/0.</p> Signup and view all the answers
