By default, split horizon is enabled.
2. Enabling poison reverse
Poison reverse allows RIP to send routes through the interface where the routes were learned, but
the metric of these routes is always set to 16 (unreachable) to avoid routing loops between
neighbors.

Enabling zero field check on incoming RIPv1 messages
Some fields in the RIPv1 message must be set to zero. These fields are called "zero fields." You can
enable zero field check on incoming RIPv1 messages. If a zero field of a message contains a non-zero
value, RIPv1 does not process the message. If you are certain that all messages are trustworthy, disable
zero field check to save CPU resources.
This feature does not apply to RIPv2 packets, because they have no zero fields.
To enable zero field check on incoming RIPv1 messages:
