Configuring RIP
9-35
2 configures an interface to send only RIPv2 packets.
3 configures an interface not to send RIP packets.
Examples
The following example configures the interface to send RIPv1 packets from the
interface:
ip rip send version 1
The next example configures the interface to send RIPv2 packets from the interface:
ip rip send version 2
This example configures the interface to receive only RIPv1 packets:
ip rip receive version 1
Enabling or Disabling Split Horizon
Routers that use distance-vector routing protocols and that connect to broadcast-type
IP networks use the split horizon with poisoned reverse mechanism to prevent routing
loops. Split horizon with poisoned reverse advertises route information with a metric
of 16 on any (unreachable) interface from which that information originated. This
usually optimizes communications among multiple routers, particularly when links
are broken.
Follow these steps to enable or disable split horizon:
1. To enable split horizon, use the ip split-horizon command in Interface
Configuration mode, as shown in the example below:
MOT(config-if)#ip split-horizon
2. To disable split horizon, use the following no ip split-horizon command in
Interface Configuration mode:
MOT(config-if)#no ip split-horizon
