It looks like recently the native
ipv6 deployment for TWC has expanded again, this time to the western New York region. I started seeing slightly more blinking from my cable modem's activity LED than I was used to seeing. I thought that maybe someone was trying something nefarious, so I logged into my Linux router to start a packet capture. Lo and behold, the "unexpected" traffic was
ipv6 multicast listener reports and router advertisements, or RAs.
rchandra@rootin:~ 1> sudo radvdump
pass phrase for rchandra on rootin:
#

AdvSendAdvert on;
# Note: {Min,Max}RtrAdvInterval cannot be obtained with radvdump
AdvManagedFlag on;
AdvOtherConfigFlag on;
AdvReachableTime 0;
AdvRetransTimer 0;
AdvCurHopLimit 64;
AdvHomeAgentFlag off;
AdvDefaultPreference medium;
AdvSourceLLAddress on;
AdvLinkMTU 1500;
}; # End of interface definition
Neat! Thanks, TWC, for the upgrade.
Now I suppose the next step is figuring out how to install and configure something on my Linux router which is able to perform a prefix delegation. WIDE-DHCP client, Dibbler, ISC maybe, I don't know yet. What's the Ubuntu 12.04 package with which you've had the best results (however you wish to define "best," but please explain)?
EDIT: One thing I had been wondering, and is finally answered: Does
ipv6 depend on seeing
ipv6 on the Motorola (SB6120) configuration page? No, it does not. "IPv4 Only" mode must mean for managing the modem itself, not what's attached to it.
