Re: Evaluation: draft-ietf-idmr-igmp-mrdisc - Multicast RouterDiscovery to Proposed Standard



Since I likely won't be on the telechat when this rolls around; I'll probably change it to "no further discussion" when it becomes clear that someone else is holding this token.

DISCUSS:

Security language should say "We are operating in a zone where security is impossible anyway, so this protocol doesn't make the net more vulnerable than it already is".
If I understand it correctly, a rogue on a link can overload that link by announcing the presence of a router on that link if other links on the switch have huge amounts of multicast sourced traffic.

COMMENTS:

I think glomming this onto IGMP may be an appropriate choice; people who do multicast on a LAN are already doing IGMP, so the choice seems no worse to me than using ICMP. But the choice of glomming it onto ND for IPv6 needs review by IPv6 experts (if it has not already had it. I just want to be reassured here :-)
