Dear all,
Having read the oDAD draft spec and in search of an answer would it be
possible if somebody can give assist with the following question?
If the MN has not sent its link-layer address (LLA) in the Neighbour
Solicitation (NS) how does the AR know the LLA of the host to forward
downstream DURING the DAD resolution period (i.e. 1000ms)?
My question tries to resolve how the forwarding can be effected
_downstream_ from AR --> host even if optimistically the node's address
configuration is accepted DURING the DAD resolution period.
If I understand correctly, forwarding in ANY direction requires a
neighbour resolution (i.e. ARP resolution v6) from an IP address to the
LLA address of the destined IP address. In my understanding this is
mandated by NUD to enable frame forwarding to the node's MAC destination.
If I see correctly the upstream link transmission from host --> AR would
be sorted out by the (oDAD) solicited NeighAdvert received by the host
which is fine..
Any answers to this would be appreciated.
many thanks
theodoros
