Configuring the Routing Information Protocol
The Ethernet Modem Router can be configured to communicate
with other routing devices to determine the best path for sending
data to its intended destination. Routing devices communicate this
information using a variety of IP protocols. This chapter describes
how to configure the Ethernet Modem Router to use one of these,
called the Routing Information Protocol (RIP).
RIP Overview
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 via the ADSL line.
Generally, RIP is used to enable communication on autonomous
networks. An autonomous network is one in which all 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 closest
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.
When should you configure RIP?
Most small home or office networks do not need to use RIP; they
have only one router, such as the Ethernet Modem Router , 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:
f Your home network setup includes an additional router or
RIP-enabled PC (other than the Ethernet Modem Router ).
The Ethernet Modem Router and the router will need to
communicate via RIP to share their routing tables.
f 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.
f Your ISP requests that you run RIP for communication with
devices on their network.
