Hi Ted,

> Fernando's draft actually suggests filtering ethertype 0x86DD in order to avoid RA attacks on switches that don't have RA guard, which is why I assumed that that was an option for IPv4-only networks that don't want to be affected by this proposal.

Ouch, a solution like that would then increase the cost of deploying IPv6 later on. I agree it is effective to prevent (rogue) IPv6 stuff, but it would be a bit too effective for my taste.

Cheers :)
