Re: The stupidity of trying to "fix" DHCPv6

I can also take down a network with spanning-tree, but oh wait, we
protect against that don't we.

Maybe protecting against rogue RA to begin with would be a better idea
than waiting until a problem happens.

Just saying.

No, I posed the easiest way to recreate this issue.

I've seen the entire NANOG and IETF lans taken out because some
dork enabled microsoft connecting sharing to their cell card.

I've seen entire corporate networks taken out because someone ran
the patch cable to the wrong port.

The point is, RA's are operationally fragile and DHCP is operationally
robust.  You can choose to stick your head in the sand about that
if you want, but it's still true.
