Hi,
I've started implementing DAT for IPv6 and I have a few questions regarding the design. I've already implemented a snooping mechanism for Network Solicitation package,
I forgot to ask here: packets generated by the IPv6 the Neigh Discovery Protocol are sent on a periodic basis, right? so what is the idea behind the snooping mechanism? There is not a request (like for ARP), right? So when should the data in distributed table be used?
From what I understood the Neighbor Solicitation and Neighbor Advertisement packets are the ARP equivalents. So if we receive a Neighbor Solicitation than we would use the distributed table and send the Neighbor Advertisement directly.
Oh ok, It was my fault. I quickly re-read part of the RFC4861: only router advertisement are sent on a periodic basis, while the neighbour advertisement is asynchronously sent either on address change or as a reply to a neighbour solicitation.
Thanks.
Cheers,
