[radvd-devel-l] Question on NDP

[Pedro Martínez]

I don't know if this is the right place to ask about some aspects 
related to the Neighbor Discovery Protocol. Actually, this is the 
closest thing I have been able to find. If you think this list is not 
suitable enough, please indicate me where I should address my doubts.

I have a problem to solve. This problem is that I need to know the MAC 
addresses of all of my neighbors by sending a single message. I though 
of NDP as a possible solution. I thought that by sending the Neighbor 
solicitation to the multicast group 
{0xff,0x02,0,0,0,0,0,0,0,0,0,0,0,0,0,1} would be enough, but it isn't 
so. My idea was sending this message to the multicast address and the 
sender would receive an answer by every neighbor receiving its request.

Can you help me with this?. Do you know any other solution to my problem?
