Configuring the Routing Information Protocol
– 519 –
versions can take a long time to converge on a new route after the
failure of a link or router during which time routing loops may occur,
and its small hop count limitation of 15 restricts its use to smaller
networks. Moreover, RIP (version 1) wastes valuable network
bandwidth by propagating routing information via broadcasts; it also
considers too few network variables to make the best routing decision.

RIP is used to specify how routers exchange routing information. When RIP
is enabled on this router, it sends RIP messages to all devices in the
network every 30 seconds (by default), and updates its own routing table
when RIP messages are received from other routers. To communicate
properly with other routers using RIP, you need to specify the RIP version
used globally by the router, as well as the RIP send and receive versions
used on specific interfaces (see
"Configuring Network Interfaces for RIP"
on page 530 ).

These parameters are displayed in the web interface:
Global Settings
◆
RIP Routing Process – Enables RIP routing globally. RIP must also be
enabled on each network interface which will participate in the routing
process as described under
"Specifying Network Interfaces" on
page 523 . (Default: Disabled)
◆
Global RIP Version – Specifies a RIP version used globally by the
router. (Version 1, Version 2, By Interface; Default: By Interface)
When a Global RIP Version is specified, any VLAN interface not
previously set to a specific Receive or Send Version (
page 530 ) is set to
the following values:
■
RIP Version 1 configures previously unset interfaces to send RIPv1
compatible protocol messages and receive either RIPv1 or RIPv2
protocol messages.
■
RIP Version 2 configures previously unset interfaces to use RIPv2
for both sending and receiving protocol messages.
