Enabling Zero Field Check On Incoming Ripv1 Messages; Enabling Source Ip Address Check On Incoming Rip Updates - HP 6125XLG Configuration Manual

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, RIP 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:
Step
1. Enter system view.
2. Enter RIP view.
3. Enable zero field check on
incoming RIPv1 messages.

Enabling source IP address check on incoming RIP updates

Perform this task to enable source IP address check on incoming RIP updates.
Upon receiving a message 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.
Upon receiving a message 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.
To enable source IP address check on incoming RIP updates:
Step
1. Enter system view.
2. Enter RIP view.
