2.4.5 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.
For a message received 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.
Follow these steps to enable source IP address check on incoming RIP updates:

 Note:
The source IP address check feature should be disabled if a RIP neighbor is not directly
connected.
2.4.6 Configuring RIPv2 Message Authentication
RIPv2 supports two authentication modes: plain text and MD5.
In plain text authentication, the authentication information is sent with the RIP message,
which however cannot meet high security needs.
Follow these steps to configure RIPv2 message authentication:
