Enabling RIP and Entering the RIP View
Perform the following configurations in System View
By default, RIP is not enabled.
Enabling RIP on a Specified Network
For flexible control of RIP operation, you can specify the interface and configure the
network on which the interface is located to the RIP network, so that these interfaces
can send and receive RIP packets.
Perform the following configurations in RIP View.
After the RIP interface is enabled, you should also specify its operating network
segment, because RIP only operates on the interface when the network segment has
been specified. RIP does not receive or send routes for an interface that is not on the
specified network, and does not forward its interface route.
When the
network command is used for an address, the effect is to enable the
interface of the network with this address. For example, for network 129.102.1.1,
you can see network 129.102.0.0 either using the
display current-configuration
command, or using the
display rip command.
By default, RIP is disabled on all interfaces.
Configuring Unicast RIP Messages
RIP is a broadcast protocol. To exchange routing information with a non-broadcast
network, unicast transmission mode must be used.
Perform the following configuration in the RIP View.
By default, RIP does not send messages to unicast addresses.
