Re: 48 bits long prefix

Hello

I'm using radvd to send RA in an IPv6 test network.

When using 64 bits long prefixes, everything works fine, my network is
functional. But when i use 48 bits long prefixes, the hosts do not
perform address autoconfiguration.

I used exactly the same configuration than with the /64...

Is it a problem or am i missing or misunderstanding something ?

As far as I know autoconf only works with /64. What would be the benefit
of using another prefix length? The 16 bits more would not be used anyway,
because the mechanism only generates 64 bit host addresses.

Best regards
