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.
Follow these steps to enable poison reverse:
To do… Use the command… Remarks
Enter system view system-view —
Enter interface view

Configuring the maximum number of load balanced routes
This task allows you to implement load balancing over multiple equal-cost RIP routes.
Follow these steps to configure the maximum number of load balanced routes:
To do… Use the command… Remarks
Enter system view system-view —
Enter RIP view rip [ process-id ] —
Configure the maximum number of
load balanced routes
maximum load-balancing number
Optional
6 by default
Enabling zero field check on incoming RIPv1 messages
Some fields in the RIPv1 message must be zero. These fields are called “zero fields”. You can enable zero
field check on received RIPv1 messages. If such a field contains a non-zero value, the RIPv1 message will
not be processed. If you are sure that all messages are trusty, disable zero field check to save CPU
resources.
This feature does not apply to RIPv2 packets that have no zero fields.
Follow these steps to enable zero field check on incoming RIPv1 messages:
To do… Use the command… Remarks
Enter system view system-view —
Enter RIP view rip [ process-id ] —
Enable zero field check on
received RIPv1 messages

Optional
Enabled by default
Enabling source IP address check on incoming RIP updates
You can enable source IP address check on incoming RIP updates.
