Routing Protocols

-
If a router learns more than 1 route to other subnet, choose the best route
React to changes when N/W topology changes. For e.g. A link fails > converge to choose the best route for each destination subnet
All routing protocols perform above tasks, but differ in how they do it
RIP
Used much less, easier to learn

R1 either removes the route from its routing table or marks the route as unusable (with an infinite metric) for a few minutes before removing the route
By the end of this process, R1 knows for sure that its old route for subnet 172.30.22.0/24 has failed, which helps R1 avoid introducing looping IP routes
