3.5.g Implement EIGRP [multi-address] named mode

  • 3.5.g [i] Types of families
  • 3.5.g [ii] IPv4 address-family
  • 3.5.g [iii] IPv6 address-family

piece of cake if you are familiar with address families…

R1(config)#do sh ver
Cisco IOS Software, 7200 Software (C7200-ADVENTERPRISEK9-M), Version 15.2(4)S, RELEASE SOFTWARE (fc1)

you’ll need a relatively new version of ios to support this

use a name instead of a number

R1(config)#router eigrp ?
<1-65535>  Autonomous System
WORD       EIGRP Virtual-Instance Name

R1(config)#router eigrp OZ

R1(config-router)#address-fam ipv4 autonomo 1
R1(config-router-af)#netw 0.0.0.0
R1(config-router-af)#
*Apr 26 14:55:15.199: %DUAL-5-NBRCHANGE: EIGRP-IPv4 1: Neighbor 192.168.12.2 (FastEthernet1/0) is up: new adjacency

older versions in address-family mode the autonomous system was configured on a separate line… now just put it on the same line with address-fam ipv4

use af-interface mode for interface specific commands:

R1(config-router-af)#af-interface

topology base mode gives you the usual manipualation set:

R1(config-router-af)#topology base
R1(config-router-af-topology)#?
