10 Configuring RIP

The HM210dp/di can be configured to communicate with other routing devices to determine the best path for sending data to its intended destination. This chapter describes how to configure your HM210dp/di to use one of these, called the Routing Information Protocol (RIP).

10.1Overview of RIP

RIP is an Internet protocol you can set up to share routing table information with other routing devices on your LAN, at your ISP’s location, or on remote networks connected to your network via the ADSL line. Generally, RIP is used to enable communication on autonomous networks. An autonomous network is one in which all of the computers are administered by the same entity. An autonomous network may be a single network, or a grouping of several networks under the same administration. An example of an autonomous network is a corporate LAN, including devices that can access it from remote locations, such as the computers telecommuters use.

Using RIP, each device sends its routing table to its closes neighbor every 30 seconds. The neighboring device in turn passes the information on to its next neighbor and so on until all devices in the autonomous network have the same set of routes.

Most small home or office networks do not need to use RIP; they have only one router, such as the HM210dp/di, and one path to an ISP. In these cases there is no need to share routes, because all Internet data from the network is sent to the same ISP gateway.

You may want to configure RIP if any of the following circumstances apply to your network:

Your network includes an additional router or RIP-enabled PC. The HM210dp/di and the router will need to communicate via RIP to share their routing tables.

Your network connects via the ADSL line to a remote network, such as a corporate network. In order for your LAN to learn the routes used within your corporate network, they should both be configured with RIP.

Your ISP requests that you run RIP for communication with devices on their network.
