2.8.5 Configuring RIP to Check the Validity of Update Packets

The check on RIP Update packets includes the check on zero fields in RIPv1 packets and the
check on source addresses of RIP Update packets. The two types of check have different
functions and applications.

Poison reverse is enabled.
Configuring the Zero Field Check for RIPv1 Packets
1. Run:
system-view
The system view is displayed.
2. Run:
rip [ process-id ]
The RIP process is enabled and the RIP view is displayed.
3. Run:
checkzero
The zero field check is configured for RIPv1 packets.
Certain fields in a RIPv1 packet must be 0s, and these fields are called zero fields.
RIPv1 checks the zero fields on receiving a packet. If the value of any zero field in a
RIPv1 packet is not 0, this packet is not processed.
As a RIPv2 packet does not contain any zero field, configuring the zero field check
is invalid in RIPv2.
Configuring the Source Address Check for RIP Update Packets
1. Run:
system-view
The system view is displayed.
2. Run:
rip [ process-id ]
The RIP process is enabled and the RIP view is displayed.
