Details
Specify the type of authentication used in Enhanced Interior Gateway Routing Protocol (EIGRP) packets per interface.
Rationale:
Configuring EIGRP authentication key-chain number and name to restrict packet exchanges between network devices.
Impact:
Organizations should plan and implement enterprise security policies that require rigorous authentication methods for routing protocols. Configuring the interface with ‘ip authentication key chain’ for EIGRP by name and number enforces these policies by restricting the exchanges between network devices.
Solution
Configure the interface with the EIGRP key chain.
hostname(config)#interface {interface_name}
hostname(config-if)#ip authentication key-chain eigrp {eigrp_as-number} {eigrp_key-chain_name}
Default Value:
Not set
