RE: IPv6 delivery model to end customers

So Cisco (and other vendors) needs to introduce two things for LAN
switching. DHCPv6 snooping, and more importantly, RA suppression (or
RA snooping).

For IOS, have you tried the command:

int gi0/1
ipv6 nd ra suppress


That stops your router from sending any RAs.
Does nothing to prevent someone else from sending them, and becoming the
default gateway for every IPv6 capable host on that link ...
