Named EIGRP for IPv6

Question

Hi,
I'm trying to do some lab testing and tested named EIGRP. I was able to understand the EIGRPv6 configuration where you configure the EIGRP statement under the interface and by issuing "no shutdown" under the EIGRP process created. So basically all IPv6 networks that has to be advertised via EIGRP has to have the "ip eigrp xxx" statement under the interface.
Now, I'm trying to do named EIGRP. By simply creating the EIGRP multi-af process and by issuing "no shutdown" under the address-family ipv6 autonomous-system, all interfaces with IPv6 address are being advertised right away and EIGRP peering gets established as well.
Is this the normal behavior? So is it a general practice to shutdown the address-family ipv6 process first and af-interface default to shutdown state, then individually turn on specific af-interface for EIGRP IPv6 processing?
Thanks,
JL

The only way I found to disable the automatic route advertisement is to shut the routing process right away after it was created. Go to IPv6 address-family and shut the af-interface default and turn on individual interface that needs to participate.  If the routing process is turned on and you added an IPv6 address-family, all interfaces with IPv6 address will automatically participate. So if you already have an IPv4 address-family running in the first place and you want to add IPv6 under the same EIGRP process then it would be ideal to plot it through notepad and paste it to ensure you can have absolute control of the IPv6 advertisement. 
That's how I see it and just correct me if I am wrong.
