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...
Enter system view
Enter RIP view
Configure the maximum
number of load balanced routes

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, you can 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...
Enter system view
Enter RIP view
Enable zero field check on
received RIPv1 messages

Enabling Source IP Address Check on Incoming RIP Updates

You can enable source IP address check on incoming RIP updates.
For a 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.
Follow these steps to enable source IP address check on incoming RIP updates:
