In OLSRv1 (that is what we are using today) this would work, but ipv6 itself 
is a problem with OLSRv1 because the address fields are getting HUGE.

In OLSRv2 (which can use address compression for address blocks) even with 
"autoconfig" it would be better to use a real subnet so that you compress the 
blocks (common header/suffix-compression).

But the IPv6 autoconfig might be a good step to get a "permanent" adderss in 
an OLSRv2 IPv6 network. :)
