3Com Switch 7750 Series
Command Reference Guide – Routing Protocol Chapter 2 RIP Configuration Commands
2-17
Use the undo rip output command to disable an interface from transmitting RIP
packets.
By default, all interfaces except loopback interfaces are enabled to transmit RIP
packets to the external.
This command is used in cooperation with another two commands: rip input and rip
work . Functionally, rip work is equivalent to rip input & rip output. The latter two
control the receipt and the transmission of RIP packets respectively on an interface.
The former command equals the functional combination of the latter two commands.
Related command: rip input, rip work.
Example
# Disable the interface Vlan-interface 10 from transmitting RIP packets.
<3Com> system-view
System View: return to User View with Ctrl+Z.
[3Com] interface Vlan-interface 10

Description
Use the rip split-horizon command to configure an interface to use split horizon
when transmitting RIP packets.
Use the undo rip split-horizon command to configure an interface not to use split
horizon when transmitting RIP packets.
By default, an interface is enabled to use split horizon when transmitting RIP packets.
Normally, split horizon is necessary for avoiding route loop. Only in some special
cases does split horizon need to be disabled to ensure the correct execution of the
protocol. So, disable split horizon only when necessary.
