In-depth discussion on the practical application of Routing Information Protocol

The configuration of the routing information protocol is still very simple. Here we mainly explain the practical application of the routing information protocol. To manage a router, you need to understand the basic language of the router, that is, the routing information protocol. The more familiar you are with basic routing information protocols, the easier it will be to diagnose faults in network routing information protocols in the future. This article is excerpted from the Informit website, which studies the basic features of the internal gateway protocol.

Route information protocol (RIP)

The routing information protocol was originally designed for Xerox PUPPARC universal protocol. In 1981, the Xerox network system protocol was collectively referred to as "GWINFO" and defined as "RFC 1988" in 1058 ". The routing information protocol is easy to configure and works very well in small networks. However, in large networks, the routing information protocol is inefficient. As I said to myself, the routing information protocol will split your network. In a large network environment, there is a protocol that replaces the routing information protocol. The routing information protocol has the following features:

1. open protocols are widely used and stable.

2. Suitable for small networks and easy to configure.

3. There is a distance vector routing information protocol similar to the routing information protocol for Novell and AppleTalk software.

4. Internal Gateway Protocol IGP)

5. IP route information protocol update sends all the RIPv2 vrouters multicast addresses 224.0.0.9 every 30 seconds through broadcast ).

6. UDP User Datagram Protocol) Port 520.

7. The manageable distance is 120.

8. A single measurement criterion is that the maximum number of computing hops is 15 and the count is infinite ).

9. The timer helps adjust performance.

Update timer-the frequency of Route updates. The complete route table is sent every 30 seconds based on the horizontal split. IPX route information protocol sends route tables every 60 seconds ). Invalid timer-No refreshed content in route update. The routing information protocol waits for 180 seconds, and then marks a route as illegal and immediately puts the route in a restrained timing state.

Keep timing and trigger updates-help with stable routing in Cisco phantom. Suppressing timing ensures that normal updates do not properly cause route loops. Vrouters do not respond to superior information within a specific period of time. The suppression time of the routing information protocol is 180 seconds. Refresh timer-the route information protocol takes an additional 240 seconds before deleting the route from the route table.
