Wireshark does not decode Secure Neighbor Discovery options in Router
Advertisements (or other IPv6 ICMPv6 headers that use this protocol).
See RFC 3971.
ICMPv6 option types, 11, 12, 13 and 14 are reported as "unknown"
Configuring SEND to test this is not straightforward. The only solution on
Linux is to use the research implementation of SEND provided by DoCoMo at
http://www.docomolabs-usa.com/lab_opensource.html.
If you want to get this working quickly then I suggest that you look in the
examples/ipext directory in the source zip file. There you will find
instructions in a PDF for using the example files. Use the example files
unchanged and setting your systems clock back to a date that makes the example
certificate valid is the quickest (dirty) way to get it working. You will still
need to create the CGA parameters file using the cgatool command in the
instructions.
Once the configuration is installed you also need to apply the IPv6 address
from the cgatool command to an interface on your machine and configure radvd to
advertise the prefix from the example files (2003::/64).
I have attached a trace which may help. There is only one packet in the trace.
