If...
The MD5 digest in the 'Authentication Data' is found
to be invalid...
Else, the packet is forwarded for the rest of the processing.

Out-bound RIP Traffic on an Interface

These are the verification criteria for all out-bound RIP packets on a RIP interface when the interface is
configured with a keychain.
If...
The keychain configured on the RIP interface exists
in the keychain database ...
The keychain is configured with a MD5 cryptographic
algorithm...
Else, RIP packets fail authentication check.

How to Implement RIP

This section contains instructions for the following tasks:
Note To save configuration changes, you must commit changes when the system prompts you.

Enabling RIP

This task enables RIP routing and establishes a RIP routing process.
Before You Begin
Although you can configure RIP before you configure an IP address, no RIP routing occurs until at least one
IP address is configured.

Then...
The packet is dropped. A RIP component-level debug
message is be logged to provide the specific details
of the authentication failure.
Then
The RIP packet passes authentication check at the
remote/peer end, provided the remote router is also
configured to authenticate the packets using the same
keychain.
