Enabling Source Ip Address Check On Incoming Rip Updates; Configuring Ripv2 Message Authentication - HP 830 Series Configuration Manual

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

WARNING!
Disable the source IP address check feature if the RIP neighbor is not directly connected. Otherwise, packet
loss might occur.
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.
3. Enable source IP address
check on incoming RIP
messages.

Configuring RIPv2 message authentication

Perform this task to enable authentication on RIPv2 messages. This feature does not apply to RIPv1
because RIPv1 does not support authentication. Although you can specify an authentication mode for
RIPv1 in interface view, the configuration does not take effect.
RIPv2 supports two authentication modes: simple authentication and MD5 authentication.
To configure RIPv2 message authentication:
Step
1. Enter system view.
2. Enter interface view.
3. Configure RIPv2 authentication.
