My Network Lab: Configuring Named EIGRP for IPv4 and IPv6

The following steps can be used to configure Named EIGRP:

Step 1: Configure a Named EIGRP virtual instance using the router eigrp <virtual-instance-
name> command in global configuration mode. It is under this single virtual instance that all address families are configured.

Step 2: Specify an address family along with an autonomous system number using the address-family <ipv4 | ipv6> autonomous-system <asn> command.

Step 3: Configure general EIGRP settings under Address-Family configuration mode. Examples of commands issued in this configuration mode include metric, network, eigrp stub, and eigrp router-id.

Step 4: (Optional) Enter Address-Family-Interface configuration mode, with the command af-interface <default | interface-id>. If you specify the default option, commands entered in this configuration mode apply to all interfaces (unless overridden by a command applied to a specific interface). Examples of commands issued in this configuration mode include authentication, bandwidth-percent, hello-interval, hold-time, passive-interface, and split-horizon.

Step 5: (Optional) Exit Address-Family-Interface configuration mode (if currently in that mode) with the exit command, and enter Address-Family-Topology configuration mode with the topology base command. Examples of commands issued in the Address-Family-Topology configuration mode include auto-summary, maximum-paths, redistribute, and variance.
