Information
Configure the EIGRP address family.
Rationale:
Rationale: EIGRP is a true multi-protocol routing protocol and the 'address-family' feature enables restriction of exchanges with specific neighbors
Solution
Configure the EIGRP address family.
hostname(config)#router eigrp <virtual-instance-name>
hostname(config-router)#address-family ipv4 autonomous-system {eigrp_as-number}
Impact:
Organizations should plan and implement enterprise security policies that require rigorous authentication methods for routing protocols. Using 'address-family' for EIGRP enforces these policies by restricting the exchanges between predefined network devices.
Default Value:
Not set
