Information
Enable authentication for Routing Information Protocol (RIP) Version 2 packets and to specify the set of keys that can be used on an interface.
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. Configuring the interface with 'ip rip authentication key-chain' by name enforces these policies by restricting the exchanges between network devices.
Solution
Configure the Interface with the RIPv2 key chain.
hostname(config)#interface {<em>interface_name</em>}
hostname(config-if)#ip rip authentication key-chain {<em>rip_key-chain_name</em>}
Default Value:
Not set
