RFC 7217 includes it specifically for the case where the node might have 2 interfaces attached to the same network, and by using an interface index (or ifname or whatever else), the node gets separate IIDs automatically.
The draft says: > If DAD fails, the 6LBR will use public values for Prefix, Interface > Index, and Network ID; the remaining two variables (DAD Counter, > Randomized Secret Key) are local values. Neighbor solicitation using > link-local address cannot be avoided, but only the newly generated > IID needs to be forwarded to the LN. How does the 6LBR get the "Interface Index" mentioned in the above text. The text says the Randomized Secret Key is a "local" value, presumably the 6LBR's own value and not the 6LN's value, but the Interface Index is not in that set, it's in the "public values" set of parameters and I don't know what that means. Is there a message where the 6LN passes its ifindex to the 6LBR? This needs to be explained in the draft. Dave
