I would like to point out that in IPv4 we have ICMP Router
Advertisement messages. I have never seen them used on a production
network. I know one of the worries is security, that a compromised host
could send out advertisements, drawing traffic to it that it can then
snoop and pass on to the real gateway.
Having not looked in great detail, I am unclear if IPv6 has done
something to fix this concern or not.
Is this feature going to get turned off when the first worm comes along
that spoofs RA's
