21 12.3: Named EIGRP Configuration

22 © Named EIGRP Configuration Classic EIGRP requires separate EIGRP configuration modes and commands. Named EIGRP Configuration is more recent method of configuring EIGRP for IPv4 and IPv6. A single mode to gather all EIGRP commands in one place. Uses address families unify EIGRP IPv4 and IPv6 configuration. Named mode is required when using EIGRP for IPv6 routing and VRFs (Virtual Routing and Forwarding).
