Details
Configure authentication to prevent unapproved sources from introducing unauthorized or false routing messages.
Rationale:
This is part of the EIGRP authentication configuration
Impact:
Organizations should plan and implement enterprise security policies that require rigorous authentication methods for routing protocols. Configuring the interface with ‘ip authentication mode’ for EIGRP by number and mode enforces these policies by restricting the exchanges between network devices.
Solution
Configure the interface with the EIGRP authentication mode.
hostname(config)#interface {interface_name}
hostname(config-if)#ip authentication mode eigrp {eigrp_as-number} md5
Default Value:
Not set
