RIP
RIP
Routing Information Protocol (RIP) is an Interior Gateway/Distance Vector Routing Protocol that uses Hop count as the metric.
- AD: 120
- Metric: Hop count
- EXAMPLE: if R1 is trying to get to R4, and it has two paths available (R1>R2>R3>R4 [3 hops] and R1>R5>R4 [2 hops]), it will add the shortest path to its routing table (R1>R5), regardless of bandwidth
- Information will get passed along with each hop passing on the route with the number of hops
- EXAMPLE: if R1 is trying to get to R4, and it has two paths available (R1>R2>R3>R4 [3 hops] and R1>R5>R4 [2 hops]), it will add the shortest path to its routing table (R1>R5), regardless of bandwidth
- The maximum hop count by default is 15
- Paths that are more than 15 hops away are marked as unreachable
- RIP is not typically used in production because of its scalability issues
- Typically only used in small or test environments
