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.
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-address parameter 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-configuration
command 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.
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
