3.3.1.4 Set 'address-family ipv4 autonomous-system'

Information

Configure the EIGRP address family.

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 <<em>virtual-instance-name</em>>
hostname(config-router)#address-family ipv4 autonomous-system {<em>eigrp_as-number</em>}

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.
