I am setting up IPv6 to be routed by a Debian 10 box. Currently I am trying to get /etc/network/interfaces to set up the upstream link to my ISP. So far I have:
Code: Select all
# WAN interface
allow-hotplug enp1s0
iface enp1s0 inet6 dhcp
accept_ra 2
request_prefix 1
This gets me a /64, which doesn't allow me to subnet and use EUI-64 addresses downstream (this is for a lab setup, so I can tolerate having everything blown away when the prefix changes). It doesn't look like the man page for the interfaces file has been updated since dhclient 4.4 came out, so maybe the option for the prefix length hint hasn't shown up yet. Or is there one, yet?
I could just subnet the /64 or use the command line and try to get a shorter prefix, but it would be nice to have one more obscure option for the interfaces file, wouldn't it?
