In Rip version 2 use Multicast Routing per Subnet: RIP-1 supported subnet entries only within the subnetted network. This enforces strict hierarchical routing. RIP-2 allows routing on the subnet outside of the network by passing subnet mask information in parallel with the address. This also allows support of variable length masks within the same network or aggregation of several class-C addresses within one address group.
RIP is an interior gateway protocol IGP that uses a distance-vector algorithm to determine the best route to a destination, using the hop count as the metric. In a RIP network, each router's forwarding table is distributed among the nodes through the flooding of routing table information. Because topology changes are flooded throughout the network, every node maintains the same list of destinations. Packets are then routed to these destinations based on path-cost calculations done at each node in the network. Distance-vector routing protocols transmit routing information that includes a distance vector, typically expressed as the number of hops to the destination. This information is flooded out all protocol-enabled interfaces at regular intervals every 30 seconds in the case of RIP to create a network map that is stored in each node's local topology database.

The Routing Information Protocol RIP is one of the oldest distance-vector routing protocols which employs the hop count as a routing metric. RIP prevents routing loops by implementing a limit on the number of hops allowed in a path from source to destination. RIP implements the split horizon , route poisoning and holddown mechanisms to prevent incorrect routing information from being propagated. In RIPv1 routers broadcast updates with their routing table every 30 seconds. In the early deployments, routing tables were small enough that the traffic was not significant. As networks grew in size, however, it became evident there could be a massive traffic burst every 30 seconds, even if the routers had been initialized at random times.
Routing Information Protocol
The update interval is the interval at which routes that are learned by RIP are advertised to neighbors. This timer controls the interval between routing updates. The update interval is set to 30 seconds, by default, with a small random amount of time added when the timer is reset. This added time prevents congestion that can occur if all routing devices update their neighbors simultaneously.
In the same simulation network topology, the simulation experiments compare RIPv1 and RIPv2 with the routing table, route update messages, route summarization, and the function of discontinuous network.
Я знаю. Коммандер медленно поднял голову. - Файл, который я скачал из Интернета… это был… Сьюзан постаралась сохранить спокойствие. Все элементы игры поменялись местами.
Внутри клубились тучи черного дыма. Все трое как завороженные смотрели на это зрелище, не лишенное какой-то потусторонней величественности. Фонтейн словно окаменел. Когда же он пришел в себя, его голос был едва слышен, но исполнен решимости: - Мидж, вызовите аварийную команду.
Мидж хмыкнула. - Кажется, чуточку дороговато, не правда. - Да уж, - застонал .
