RIP

RIP is a distance-vector routing protocol that

  • uses hop count as the metric for path selection

  • exchanges RIP broadcasts with neighboring devices to dynamically learn and advertise routes.

  • includes four basic components: routing update process, RIP routing metrics, routing stability, and routing timers.

RIP characteristics and versions

The Routing Information Protocol (RIP) is one of the most enduring routing protocols. It sends routing updates periodically and during topology changes. The packets that RIP sends include network reachability and hop count to destinations. RIP generates more traffic and is easier to configure than OSPF. It supports both Version 1 and 2.

The Secure Firewall Threat Defense device supports both RIP Version 1 and RIP Version 2. RIP Version 1 does not send subnet masks with its updates, while Version 2 supports variable-length subnet masks and neighbor authentication to ensure trusted routing information exchanges.

RIP offers simple configuration and adapts to topology changes, unlike static routes, which require updates for each change. However, it incurs higher network and processing overhead compared to static routing.
