Details
Configure authentication to prevent unapproved sources from introducing unauthorized or false service 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. Using the ‘authentication mode’ for EIGRP address-family or service-family packets enforces these policies by restricting the type of authentication between network devices.
Solution
Configure the EIGRP address family authentication mode.
hostname(config)#router eigrp
hostname(config-router)#address-family ipv4 autonomous-system {eigrp_as-number}
hostname(config-router-af)#af-interface {interface-name}
hostname(config-router-af-interface)#authentication mode md5
Default Value:
Not defined
