Which gets to the crux of my question.
If you're a shop that uses such features today (MAC/Port tracking,
DHCP snooping, etc) to "secure" your IPv4 infrastructure does IPv6
RA's represent a step backwards from a security perspective? Would
IPv6 deployment be hindered until there is DHCPv6 snooping and
DHCPv6 is able to provide a default gateway, a-la how it is done
today in IPv4?
It would be very interesting to me if the answer was "it's moot
because we're going to move to CGA's as a step forward"; it would
be equally interesting if the answer is "CGA isn't ready for prime
time / we can't deploy it for xyz reason, so IPv6 is less secure
than IPv4 today and that's a problem."
