(usagi-users 03318) Re: How do I do ARP for IPv6 in USAGI?

Hi Patrick,
I can only answer the following question.

You can add the IPv6Address and corresponding MAC Address as below:

  Add neighbors using "ip"

    ip -6 neigh add <IPv6 address> lladdr <link-layer address> dev <device>
       e.g: (At the prompt) ip -6 neigh add fec0::1 lladdr 
02:01:02:03:04:05 dev eth0

The following are For your information

  Displaying neighbors using "ip"

       ip -6 neigh show
       fe80::201:23ff:fe45:6789 dev eth0 lladdr 00:01:23:45:67:89 router 
nud reachable


  Delete neighbors using "ip"

    ip -6 neigh del <IPv6 address> lladdr <link-layer address> dev <device>
       e.g: ip -6 neigh del fec0::1 lladdr 02:01:02:03:04:05 dev eth0

Hope this would be of help to you.
