Information
Configure the Interface with the RIPv2 key chain.
Rationale:
This is part of the RIPv2 authentication setup
Impact:
Organizations should plan and implement enterprise security policies that require rigorous authentication methods for routing protocols. Using the 'ip rip authentication mode md5' enforces these policies by restricting the type of authentication between network devices.
Solution
Configure the RIPv2 authentication mode on the necessary interface(s)
hostname(config)#interface <<em>interface_name</em>>
hostname(config-if)#ip rip authentication mode md5
Default Value:
Not set
