Configure the poison reverse
The poison reverse function allows an interface to advertise the routes received by
itself, but the metric of these routes is set to 16, making them unreachable.

Some fields in the RIP-1 message must be zero. These fields are called zero fields.
You can enable the zero field check on received RIP-1 messages. If any such field
contains a non-zero value, the RIP-1 message will not be processed. If you are sure
that all messages are trusty, you can disable the zero field check to save the CPU
processing time.
In addition, you can enable the source IP address validation on received messages.
For the message received on an Ethernet interface, RIP compares the source IP
address of the message with the IP address of the interface. If they are not in the
same network segment, RIP discards the message. For a message received on a
serial interface, RIP checks whether the source address of the message is the IP
address of the peer interface. If not, RIP discards the message.
Follow these steps to enable zero field check on RIPv1 messages:
