IPv6 临时地址未续订

我的 Debian 机器出现了一些奇怪现象：IPv6 临时地址在其生命周期结束时不会更新，它们将被弃用并且变得毫无用处：

   tchupy@Raspihole:~ $ ip -6 addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 state UNKNOWN qlen 1000
    inet6 ::1/128 scope host
       valid_lft forever preferred_lft forever
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 state UP qlen 1000
    inet6 2a01:aaaa:bbb:cccc:xxxx:xxxx:53e1:eb8c/64 scope global temporary deprecated dynamic
       valid_lft 1763sec preferred_lft 0sec
    inet6 2a01:aaaa:bbb:cccc:xxxx:xxxx:fe56:f540/64 scope global deprecated dynamic mngtmpaddr
       valid_lft 1763sec preferred_lft 0sec
    inet6 2a01:aaaa:bbb:cccc::100/64 scope global noprefixroute
       valid_lft forever preferred_lft forever
    inet6 fe80::xxxx:17d/64 scope link
       valid_lft forever preferred_lft

如果我关闭/不关闭接口，它会获得一个新的临时 IPv6，但最终会失败。我不明白我错过了什么。以下是 sysctl 变量的摘录

tchupy@Raspihole:~ $ sudo sysctl -a | grep net.ipv6.conf.eth0
net.ipv6.conf.eth0.accept_dad = 1
net.ipv6.conf.eth0.max_addresses = 16
net.ipv6.conf.eth0.accept_ra = 1
net.ipv6.conf.eth0.temp_prefered_lft = 3600
net.ipv6.conf.eth0.temp_valid_lft = 14800
net.ipv6.conf.eth0.use_oif_addrs_only = 0
net.ipv6.conf.eth0.use_tempaddr = 2

任何帮助将不胜感激 ：）

谢谢
