Re: New Version Notification for draft-petrescu-6man-ll-prefix-len-17.txt

Hi Alex

The draft looks good.

In the security section can we add some recommendations for first hop security to protect IPv6 only networks using any DHCPv6 stateful or stateless scenario combinations using security features such as IPv6 snooping, IPv6 source guard to deny traffic from unknown sources and RA guard to only allow RA to be sent from the trusted L2 uplinks to the FHRP routers on the subnet.

Thank you
