After many hours of googling, I'm coming to the forums with a question.

On a server that just recently had CentOS installed on it, bonded interfaces with vlans created, and IPv6 configured on the upstream switch I get the following info:

[root@server1A ~]# ip -6 route show

Happy IPv6 Day!

ha. Nice bump tarun

6/8/2011 10:20:11 AM

the other ipv6 thread was from 2007. i have been learning about ipv6 from so long and now is the time!

haha, thread left behind.

I got a perfect score on the IPv6 Eye Chart: http://ipv6eyechart.ripe.net/

6/8/2011 3:25:47 PM

english holmes we are not all computer wizzes

6/8/2011 10:24:11 PM

It meant that my IPv6 connection was working just fine, so on that day when most of the Web will need to go dual-stack to accommodate the IPv6-only clients (and that later day when much of the Web will go IPv6-only), I'll be doing just fine.

6/8/2011 10:41:00 PM

yeah, I figured out the answer so I never answered my own thread.

built some test boxes & networks, and did some exploring. There is no detrimental effect.


and thanks for the bump.
