The route information protocol is based on the distance vector route agreement, usually using jumps as a measure, is an internal gateway agreement, is the most widely used route agreement, is the criterion for the choice of route information between the gateway and the host, and the rip is an internal gateway agreement。
I. As an internal gateway agreement or igp, route selection protocols are applied to as systems. There are specific protocols to connect to as systems, the earliest of which is egp, which is still used on the internet and is usually considered internal as route selection protocols。
Ii. Rips are primarily designed to work with modest networks using similar technologies. Thus, the rip is more suitable for simple, but not complex, campus and regional networks, through connections that vary little at a speed。
Iii. Rip 2 comes from rip, which is a supplementary agreement to the rip 2 agreement and is used primarily to expand the amount of useful information for the rip 2 information load while increasing its safety. Rip 2 is a udp-based agreement. Under rip2, each host sends and receives a package from the udp port 520 via the route selection process。
Iv. The rip protocol was originally designed for the xerox parc common protocol for the xerox network system, and is commonly used in the internet. The rip uses distance vector algorithms, i. E., routers select routes based on distance, so it is also known as the distance vector protocol, which collects all the different paths to reach the destination and keeps information on the path to the minimum number of stations at each destination, and discards any information other than the best path to the destination。
5. Concurrent routers also use rip protocols to notify neighbouring routers of the collected route information. Thus, the correct route information is gradually spreading to the entire network, and the rip is widely used and is simple, reliable and easy to configure. However, the rip applies only to small contours, as it allows a maximum of 15 stations, any destination of more than 15 sites is marked as unattainable, and rip is broadcast every 30s by means of information, which is one of the major causes of the broadcasting storm of the network。
As a result of the above presentation, it is believed that the information selection protocol for routers should be understood。
