既存のIPv4インターフェイスにIPv6アドレスを追加しても機能しません。

おそらく簡単な答えがあるようですが、見つからないようです。私はマルチホームDebian Stable（最新）を実行しており、インターフェースeth1にはIPv4とIPv6アドレスが必要です。私の/etc/network/interfacesは次のとおりです。

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

source /etc/network/interfaces.d/*

# The loopback network interface
auto lo
iface lo inet loopback

auto eth0
allow-hotplug eth0
iface eth0 inet dhcp

auto eth1
iface eth1 inet static
        address 192.168.1.2
        netmask 255.255.255.0
        gateway 192.168.1.1
        up ip -6 address add 2001:470:28:5b2::1/64 dev $IFACE

問題は、インターフェイスにIPv6アドレスではなくIPv4アドレスのみが割り当てられることです。私は何を見逃していますか？

走っている間ifup-av:

eth1が設定されていてIPv6アドレスを追加できないようですが、baspromptでこれを行うと機能します。

sudo ip -6 addr add 2001:470:28:5b2::1/64 dev eth1

そして確認ifconfig eth1:

g00nz@debie:~$ sudo ip -6 addr add 2001:470:28:5b2::1/64 dev eth1
g00nz@debie:~$ sudo ifconfig eth1

誰でも？ :(

/わかった

さて、一度試してみて、これを私の/ etc / network / interfacesに追加してください：

auto eth1
iface eth1 inet static
        address 192.168.1.2
        netmask 255.255.255.0
        gateway 192.168.1.1

iface eth1 inet6 static
        address 2001:470:28:5b2::1
        netmask 64

ところで確認してみるとIPワン私は持っています：

3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
    link/ether 00:24:9b:08:4b:aa brd ff:ff:ff:ff:ff:ff
    inet 192.168.1.2/24 brd 192.168.1.255 scope global eth1
       valid_lft forever preferred_lft forever
    inet6 fe80::224:9bff:fe08:4baa/64 scope link
       valid_lft forever preferred_lft forever

私は主張しません：（

ifup でまだエラーが発生します。
