Click on the
RIP
link to view the Routing Information Protocol
(RIP) Configuration table. Routers on your LAN communicate
with one another using the Routing Information Protocol.
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 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 closest
neighbour every 30 seconds. The neighbouring device in turn
passes the information on to its next neighbour and so on until
all devices in the autonomous network have the same set of
routes.
This table lists any interfaces on your device that use RIP
(typically the LAN interface), and the version of the protocol
used. Click on the
trashcan
icon to delete a RIP interface. Click
on the
Global Stats
icon to view the NAT statistics. This table
will open in a new window.

RIP Status
: Select the
Enable
or
Disable
radio button in
order to use the protocol.
Age
: This s the amount of time in seconds that the device's
RIP table will retain each route that it learns from adjacent
computers.
Update Time
: This specifies how frequently the
ADSL/Ethernet router will send out its routing table to its
neighbours.
IF Name
: Select an interface name from the drop-down list.
Metric
: Enter a metric value. RIP uses a hop count as a
way to determine the best path to a given destination in the
network. The hop count is the sum of the metric values
assigned to each port through which data is passed before
reaching the destination. Among several alternative routes,
the one with the lowest hop count is considered the fastest
path. For example, if you assign this port a metric of 1, then
RIP will add 1 to the hop count when calculating a route
that passes through this port. If you know that
communication via this interface is slower than through
other interfaces on your network, you can assign it a higher
metric value than the others. You can select any integer
from 1 to 15.
Send/Receive Mode:
Select a Send and Receive mode
from the drop-down list. The Send Mode setting indicates
the RIP version this interface will use when it sends its
route information to other devices. The Receive Mode
setting indicates the RIP version(s) in which information
must be passed to the ADSL/Ethernet router in order for it
to be accepted into its routing table. RIP version 1 is the
original RIP protocol. Select RIP1 if you have devices that
communicate with this interface that understand RIP
version 1 only. RIP version 2 is the preferred selection
because it supports "classless" IP addresses (which are
used to create subnets) and other features. Select RIP2 if
all other routing devices on your LAN support this version
of the protocol.
