Rip Split-Horizon - Huawei Quidway S3900 series Command Manual

Command Manual – Routing Protocol
Quidway S3900 Series Ethernet Switches-Release 1510
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.
<Quidway> system-view
System View: return to User View with Ctrl+Z.
[Quidway] interface Vlan-interface 10
[Quidway-Vlan-interface10] undo rip output

Syntax
rip split-horizon
undo rip split-horizon
View
Interface view
Parameter
None
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.
Example
# Specify the interface Vlan-interface 10 not to use split horizon when processing RIP
packets.
