3Com Switch 8800 Family Configuration Guide

294 CHAPTER 30: RIP CONFIGURATION
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.
Configuring Unicast of
the Packets
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.
Configuring Split
Horizon
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.
Setting Additional
Routing Metric
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.
Tabl e 255 Configure unicast of the packets
Operation Command
Configure unicast of the packets peer ip-address
Cancel unicast of the packets undo peer ip-address
Tabl e 256 Configure Split Horizon
Operation Command
Enable split horizon rip split-horizon
Disable split horizon undo rip split-horizon
Tabl e 257 Set additional routing metric
Operation Command
Set the additional routing metric of the route when the interface
receives an RIP packet
rip metricin value
Disable the additional routing metric of the route when the interface
receives an RIP packet
undo rip metricin
Set the additional routing metric of the route when the interface
sends an RIP packet
rip metricout value
