Hi, While going through the draft, I noticed there is no talk of
tunneled ND message in the entire draft. The draft states: - By setting the Hop Limit to 255, Neighbor Discovery is immune to off-link senders that accidentally or intentionally send ND messages.However if we send a basic ND message in IP-in-IP tunneled packet and send the packet across, we can easily send ND messages off-link. A solution I can think of is that by default we SHOULD NOT allow ND packets inside tunneled packets unless explicitly configured to do so. Am I missing the point?Thanks,Vishwas |
