Routing Information Protocol uses broadcast User Datagram Protocol (UDP) data packets to exchange routing information. Cisco IOS software sends routing information updates every 30 seconds, which is termed advertising.If a router does not receive an update from another router for 180 seconds or more, it marks the routes served by the nonupdating ( Read more... )

The IP Summary Address for RIP feature enables Cisco routers running RIPv2 to advertise a summarized local IP address pool on a network access server so that the address pool can be provided to dialup clients. For example, if a local IP address pool of 10.1.1.1 to 10.1.1.254 is configured on the network access server, you could configure the ip ( Read more... )

Характеристики протокола:

• RIPv1 и RIPv2 используют UDP порт 520.
• RIPng использует UDP порт 521.
• Для передачи сообщений RIPv1 в адресе получателя используется широковещательный адрес 255.255.255.255, а RIPv2 - мультикаст адрес 224.0.0.9.
