RIP 91

By default, RIP is not enabled.

Enabling the RIP Interface

For flexible control of RIP operation, you can specify the interface and configure the network where it is located in the RIP network, so that these interfaces can send and receive RIP packets.

Perform the following configurations in RIP view.

Table 84 Enabling RIP Interface

Operation	Command
Enable RIP on the specified network interface	network network-address
Disable RIP on the specified network interface	undo network network-address

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.

The network-addressparameter is the address of the enabled or disabled network, and it can also be configured as the IP network address of the appropriate interfaces.

When a network command is used for an address, the effect is to enable the interface of the network with the address. For example, for network 129.102.1.1, you can see network 129.102.0.0 using either the display current-configurationcommand or the display rip command.

Configuring Unicast RIP Messages

RIP is a broadcast protocol. To exchange route information with the non-broadcast network, the unicast transmission mode must be adopted.

Perform the following configuration in the RIP view.

Table 85 Configuring Unicast RIP Messages

Operation	Command
Configure unicast RIP messages	peer ip-address
Cancel unicast RIP messages	undo peer ip-address

By default, RIP does not send messages to unicast addresses.

Usually, this command is not recommended because the opposite side does not need to receive two of the same messages at a time. It should be noted that the peer command should also be restricted by the rip work, rip output, rip input and network commands.

Specifying the RIP Version

RIP has two versions, RIP-1 and RIP-2. You can specify the version of the RIP packet processed by the interface.

RIP-1 broadcasts the packets. RIP-2 can transmit packets by both broadcast and multicast. By default, multicast is adopted for transmitting packets. In RIP-2, the
