Configuring The Maximum Number Of Ecmp Routes; Enabling Zero Field Check On Incoming Ripv1 Messages - HP 830 Series Configuration Manual

To enable split horizon:
Step
1. Enter system view.
2. Enter interface view.
3. Enable split horizon.
Enabling poison reverse
Poison reverse allows RIP to send routes through the interface where the routes were learned. The metric
of these routes is always set to 16 (unreachable) to prevent routing loops between neighbors.
To enable poison reverse:
Step
1. Enter system view.
2. Enter interface view.
3. Enable poison reverse.

Configuring the maximum number of ECMP routes

Perform this task to implement load sharing over ECMP routes.
To configure the maximum number of ECMP routes:
Step
1. Enter system view.
2. Enter RIP view.
3. Configure the maximum
number of ECMP routes.

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:
