Package: ifupdown
Version: 0.8.44+deb13u1
Severity: important
Tags: ipv6
X-Debbugs-Cc: [email protected]
In its current form, /etc/network/interfaces doesn't offer any way to tell a
WAN interface where to delegate an IPv6 prefix. DHCPv6-PD is supported by
dhcpcd, dhclient and wide-dhcpv6-client, all of which are supported by
ifupdown. The only thing missing is an /etc/network/interfaces option. The
syntax I propose:
iface enp3s0 inet6 dhcp
ipv6pd br0
In the above example, WAN interface enp3s0 delegates a prefix to LAN interface
br0.
The way each DHCPv6 client expects PD options is slightly different. See
DHCP6C(8) and DHCP6C.CONF(5), DHCPCD(8) and DHCPCD.CONF(5), DHCLIENT(8) and
DHCLIENT.CONF(5), respectively.
