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).
10.1 Overview 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.
