Information
Defines user defaults to apply to EIGRP interfaces that belong to an address-family.
Rationale:
Part of the EIGRP address-family setup
Solution
Configure the EIGRP address family.
hostname(config)#router eigrp <virtual-instance-name>
hostname(config-router)#address-family ipv4 autonomous-system {eigrp_as-number}
hostname(config-router-af)#af-interface default
Impact:
Organizations should plan and implement enterprise security policies that require rigorous authentication methods for routing protocols. Using 'af-interface default' for EIGRP interfaces enforces these policies by restricting the exchanges between predefined network devices.
Default Value:
Not set
