ONFIGURATION

Note that the operating network segment must be specified after RIP is enabled. 
RIP only operates on the specified network segment. For an interface not on the 
specified network segment, RIP neither receives and send routes on it nor forwards 
its interface route, just as the interface does not exist. The network-address is an 
enabled or disabled network address, or an IP network address on each interface.

When the command 

 is used for an address, the interface of the network 

with this address is enabled. For example, for network 129.102.1.1, you can see 
network 129.102.0.0 either using 

 or using 

 command.

By default, RIP is disabled on all networks.

Generally, RIP forwards packets in broadcast addresses. In order to exchange 
routing information on a link not supporting broadcast packets, it is necessary to 
adopt unicast transmission.

Perform the following in the RIP View.

By default, RIP does not send any packet to any unicast address.

It should be noted that 

peer

 is also restricted by 

, 

, 

 and 

 commands.

Split horizon means that the route received via an interface will not be sent via this 
interface again. It avoids the creation of routing loop to some extent. But in some 
special cases, split horizon must be disabled so as to get correct advertising at the 
cost of efficiency. Disabling the split horizon has no effect on the point-to-point 
connected links but is applicable on the Ethernet.

Perform the following configuration in interface view.

By default, split horizon of the interface is enabled.

Additional metrics is the input or output metrics added to an RIP route. It does not 
change the metric value of the route in the routing table, but adds a specified 
metric value when the interface receives or sends a route.

Disable RIP on the specified network
