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 710).
Command Usage
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 (page 710).
Parameters
These parameters are displayed:
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 703. (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 710) 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.
RIP send/receive versions set on the RIP Interface settings screen (page 710)
always take precedence over the settings for the Global RIP Version. However,
when the Global RIP Version is set to “By Interface,” any VLAN interface not
previously set to a specific receive or send version is set to the following default
values:
■
Receive: Accepts RIPv1 or RIPv2 packets.
■
Send: Route information is broadcast to other routers with RIPv2.
