Ok, firstly, I have dropped using the alias notation and am now working solely
on eth0.
Secondly, yes, I am talking about provisioning more than *one* IP at a time as
being a "range".
As for IPV6ADDR_SECONDARIES, when I use the following config:
/etc/sysconfig/network-scripts/ifcfg-eth0:
DEVICE=eth0
IPADDR=***.***.***.***
NETMASK=255.255.255.0
BROADCAST=***.***.***.***
ONBOOT=yes
IPV6INIT=yes
IPV6ADDR="2001:0470:0103:001A::2/64"
IPV6ADDR_SECONDARIES="2001:0470:0103:001A::3-2001:0470:0103:001A::FFFF"
IPV6_AUTOCONF=no
IPV6_ROUTER=no
IPV6FORWARDING=no
PEERDNS=no
VLAN=no
I get the following error:
Shutting down interface eth0: [ OK ]
Shutting down loopback interface: [ OK ]
Bringing up loopback interface: [ OK ]
Bringing up interface eth0: ERROR : [ipv6_test_ipv6_addr_valid] Given IPv6

I also tried the following config:
/etc/sysconfig/network-scripts/ifcfg-eth0:
DEVICE=eth0
IPADDR=***.***.***.***
NETMASK=255.255.255.0
BROADCAST=***.***.***.***

IPV6_ROUTER=no
IPV6FORWARDING=no

And receive the following error:

After doing some digging in the ifup-ipv6 and network-functions-ipv6 scripts, it
doesn't appear that IPV6ADDR_SECONDARIES actually supports the X-Y notation in
the current release. I see no where that the hyphen is removed and a range is
generated. I'm not the most powerful bash scripter in the world, so I could be
wrong.
Can anyone else weigh in on the subject and provide some more insight? It would
be really nice to provision an entire range of IPv6 and not have to add them one
by one.
