Hi all,

Can someone explain me when do I have to use the option "address families" in Eigrp?

thanks.

Hi,

You would use address families in EIGRP configuration when doing a named-style of EIGRP configuration (that is, router eigrp ProcessName). Under this process, you could start one EIGRP instance for IPv4 using the address-family ipv4 and another one using address-family ipv6 and do all the necessary configuration under these address families.

Basically, the address family is nothing more than just a way of telling what EIGRP instance, either IPv4-based or IPv6-based, you want to start and configure.

Best regards,
Peter

Hello Peter,

This is my config, and then I add it to my interfaces. do I need to add the address families?

router eigrp Network

Hi opnineopnine,

as per Peter Paluch, we need to configure "address-family" to specify ipv4 or ipv6 then choosing between unicast/multicast or vrf, prior to configuring your preferred autonomous-system.. --- which i think is more relevant to IOS products.

router eigrp NAME

  address-family [ipv4 | ipv6] [unicast | multicast | vrf ]
  autonomous-system 10

if you want to add your preferred interface to join an eigrp process, 

you can configure the ff:

interface gigabitethernet X/Y

ip router eigrp NAME

In NX-OS eigrp feature has some changes. 

see below link for reference of commands for EIGRP in NX-OS

you can add address-families command if we are planning to run multiple instances of EIGRP on your device.
