Hi Nick,
thanks for your response.
I was wondering though, that assuming in a net where the AR has to deal
with hundreds or thousands of nodes on the link (i.e. the replenishment
rate of new nodes - with the total staying roughly the same - (as the
case may be for mobile nodes under MIPv6), how is the AR supposed to
deal with 'remembering' the LLA of all the nodes' LLA if the overiding
flag is set to zero (O=0)?.
The reason I am asking is because if the respective NCE cannot be
overidden with the NA LLA content (sent from the node), then how will
the AR 'remember' which LLA to map to when there is traffic destined
downstream for the node..?

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)?
Hi Theo,
the AR simply sends an NS (from its unicast address) to the host,
when you say to the 'host' do you mean the solicited-nodes multicast
address or the unicast address of the host? This is a bit unclear from
the spec.
Also can you see a potential denial of service attack if the node
decides to change optimistically its address continuously?
thanks
