Hi.
I'm trying to get a working freebsd workstation with an ipv6 network where
addresses are received from DHCP.
ATM my IPv6 setup copies the IPv4 layout with vlans and /24 masks, so I'm
using /120 prefixes.
Is that even possible ?
As the Handbook lacks any information about such setup, I decided to ask for
help here.
why not just use /64 prefixes ? You have 16 bits in your /48 to each
ipv4 /24 network to an ipv6 /64 network.
Don't fight the system.

Currently I'm having problems with prefixes.
I'm using the net/isc-dhcp41-client port (as the dhclient from the base
system is unable to work with DHCPv6).
I have a working rtadvd on a router, and a working DHCPv6 setup.
But my client FreeBSD still gets 64 prefix length, with or without running
rtsold.
Since DHCPv6 doesn't advertise any routing information at all (including the
prefix information), and its only function is to provide the client with an
address, I assume that the prefix information has to be received from the
router advertisements. I am currently looking at the wireshark dump, and it
appears that my workstation is receiving such advertisements. However it
doesn't affect the 64 prefix displayed in ifconfig, and all operation
involving the nodes outside the actual link are simply not working.
Also I want to say that other operating systems on the same link are working
properly (for example they can exchange with nodes in other networks).
Thanks.
