I think the problem comes from thinking that it's reasonable to have two (or more) stanzas per interface. The syntax of /etc/network/interfaces should permit complete configuration of an interface within a single stanza.
So, for the moment, the "ugly workaround" is best: iface br0 inet static address 192.168.14.1 netmask 255.255.0.0 bridge_ports eth0 up ifconfig br0 add 2001:8e0:abcd:5d7::1/64 An extension to the /etc/network/interfaces syntax might look like this: iface br1 inet address 192.168.14.1/16 inet gateway 192.168.1.255 inet6 address 2001:8e0:abcd:5d7::1/64 bridge_ports eth0 An automatically configured ipv4+ipv6 bridge interface might look like this: iface br2 inet dhcp bridge_ports eth0 (the kernel will configure the ipv6 address when it receives a router advertisement packet).
