ONFIGURATION

When a command network is used for an address, you can enable the network 
address of the port, which also includes the subnet addresses. For example, for 
network 129.102.1.1, you can see network 129.102.0.0 either using display 
current-configuration or using display rip command.

By default, RIP is disabled on all the interfaces after it is started up.

Usually, RIP sends packets using broadcast or multicast addresses. It exchanges 
routing information with non-broadcasting networks in unicast mode.

Perform the following configuration in RIP view.

By default, RIP does not send any packets to any unicast addresses.

It should be noted that a peer should also be restricted by rip work, rip output, 
rip input and network when transmitting packets.

Split horizon means that the route received via an interface will not be sent via this 
interface again. To some extent, the split horizon is necessary for reducing routing 
loop. 

Perform the following configuration in interface view.

By default, split horizon of the interface is enabled.

Additional routing metric is the input or output routing metric 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.

Perform the following configuration in interface view.
