This is working perfectly now, and the advice within is pitched perfectly at the new user setting it up for the first time. The ND prefix and the delegation prefixes are on the right interfaces, and have managed to get another machine routing ipv6 through the (router) device, also on the /48 prefix. That particular machine is using slaac to grab its ipv6. The router is still running slaacd. I'll need to test whether it still works if slaacd is deactivated, but that can wait till later. thanks,

The ISP stated the ND is used to automatically assign an ip to the wan interface of the router, so this will (will it?) mean cnmac1. That will mean pppoe0 unless they are doing something unusual. OK, thanks for clarifying. I doubt my ISP are doing anything unusual. /etc/hostname.cnmac1 has the following: up mtu 1508 inet6 autoconf /etc/hostname.pppoe0 : inet 0.0.0.0 255.255.255.255 NONE mtu 1500 \ pppoedev cnmac1 authproto chap \ authname 'mylogin@isp' authkey 'correct-password' up dest 0.0.0.1 !/sbin/route add default -ifp pppoe0 0.0.0.1 inet6 eui64 !/sbin/route add -inet6 default -ifp pppoe0 fe80::%pppoe0 I'm not sure if the last couple of lines are correct. You can either use autoconf on pppoe0, or have dhcpcd handle ND as well. See dhcpcd's pkg-readme file. OK, I'll try autoconf first. Thanks for writing.

dual stack native ipv4 & ipv6 pppoe configuration questions
Hello, My connection has a /64 Neighbour Discovery (ND) for the pppoe connection and a /48 Prefix Delegation (PD) for the LAN. (ipv4 works fine) The parent interface of the pppoe connection is cnmac1 The LAN interface is cnmac0. (cnmac2 is present but unused and there is no /etc/hostname.cnmac2) 1. do I use slaac for the pppoe/cnmac1 and dhcpcd for cnmac0 ? The ISP stated the ND is used to automatically assign an ip to the wan interface of the router, so this will (will it?) mean cnmac1. /etc/hostname.cnmac1 has the following: up mtu 1508 inet6 autoconf /etc/hostname.pppoe0 : inet 0.0.0.0 255.255.255.255 NONE mtu 1500 \ pppoedev cnmac1 authproto chap \ authname 'mylogin@isp' authkey 'correct-password' up dest 0.0.0.1 !/sbin/route add default -ifp pppoe0 0.0.0.1 inet6 eui64 !/sbin/route add -inet6 default -ifp pppoe0 fe80::%pppoe0 I'm not sure if the last couple of lines are correct. 2. I guess the way forward will ge to firstly get the ND working on the cnmac1/pppoe0 interface? Thanks in advance for any assistance.
