5.4 Named EIGRP Configuration Modes

Here are some comments about the structure of Named EIGRP Configuration.

There are three main address-family configuration modes:

• Configuration Mode – requires address-family configuration including protocol (ipv4/ipv6), AS, and optional unicast/multicast and VRF. Includes commands that pertain to the general deployment and operation of EIGRP.
  • router-id
  • network
  • eigrp stub
• Interface Mode – configured within the context of the address-family configuration mode. All commands in classic EIGRP previously configured on a per-interface basis appear here.
  • summary-address
  • passive-interface
  • hello-interval
  • hold-time
  • authentication
• Topology Mode – also configured within the context of the address-family configuration mode. All commands related to the overall EIGRP topology appear here. (Generally, all commands that affect the EIGRP topology table would appear in this section.)
  • variance
  • maximum-paths
  • redistribute

Note: Where ipv6 had to be explicitly enabled via no shutdown command in classic EIGRP mode, the named EIGRP instance does not require this manual intervention. Merely configuring the ipv6 address-family will automatically enable its operation.

Note: Since ipv6 address-family configuration automatically enables EIGRP on all ipv6-enabled interfaces by default, you should use passive-interface configuration to restrict operations where necessary.
