Enabling Source Ip Address Check On Incoming Rip Updates; Configuring Ripv2 Message Authentication; Specifying A Rip Neighbor - HP MSR2000 series Configuration Manual

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.
IMPORTANT:
Disable the source IP address check feature if the RIP neighbor is not directly connected.
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

In a network requiring high security, configure this task to implement RIPv2 message validity check and
authentication. 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 simple authentication and MD5 authentication.
To configure RIPv2 message authentication:
Step
1. Enter system view.
2. Enter interface view.
3. Configure RIPv2
authentication.

Specifying a RIP neighbor

Usually, RIP sends messages to broadcast or multicast addresses. On non-broadcast or multicast links,
you must manually specify RIP neighbors.
Follow these guidelines when you specify a RIP neighbor:
Do not use the peer ip-address command when the neighbor is directly connected because the
•
neighbor may receive both the unicast and multicast (or broadcast) of the same routing information.
If a specified neighbor is not directly connected, then disable the source address check on incoming
•
updates.
To specify a RIP neighbor:
Command
system-view
rip [ process-id ] [ vpn-instance
vpn-instance-name ]
validate-source-address
Command
system-view
interface interface-type interface-number
rip authentication-mode { md5 { rfc2082 [ cipher ] key-string key-id |
rfc2453 [ cipher ] key-string } | simple [ cipher ] password }
