Introduction to the RIP Routing Protocol

We will summarize some of the features of the RIP routing protocol. We hope to help you consolidate your basic knowledge in this area. The RIP routing protocol is a dynamic routing protocol. So I don't know if you have clearly defined his concepts and features.

RIP

(RIP) is the first open standard used by router manufacturers. It is the most extensive routing protocol and can be obtained on all IP routing platforms. When RIP is used, a Cisco router can be connected to a router of another manufacturer. RIP has two versions: r1_1 and r1_2, which are based on the classic distance vector routing algorithm and have a maximum of 15 hops.

R12001 is a family-type route Classful Routing protocol. Because mask information is not included in the route, all devices on the network must use the same subnet mask. VLSM is not supported. R12002 can send subnet mask information, non-family Routing Classless Routing) protocol, supports VLSM.

RIP uses UDP data packets to update route information. The router updates the route information once every 30 s. If no response is received from the neighboring router within S, the route to the router is considered unavailable and the router cannot arrive. If you do not receive a response from the vro after S, delete the route information about the vro from the route table.

RIP has the following features:

◆ Routers of different manufacturers can be interconnected through RIP;

◆ Simple configuration;

◆ Applicable to small networks with less than 15 hops );

◆ R1_1 does not support VLSM;

◆ Wan bandwidth consumed;

◆ CPU and memory resources need to be consumed.

The algorithm of the RIP routing protocol is simple, but the convergence speed is slow when many paths exist. When route information is broadcast, many bandwidth resources are occupied, it is suitable for small networks with relatively simple network topology and extremely low data link failure rate. In large networks, RIP is generally not used.
