Netplan 未禁用 IP v6

我的 netplan 文件中有以下内容（/etc/netplan文件夹中只有一个）

network:
 ethernets:
    enp4s0f0:
        dhcp4: false
        dhcp6: false
    enp4s0f1:
        dhcp4: false
        dhcp6: true
    enp4s0f2:
        dhcp4: true
        dhcp6: true

这是输出ip a

2: enp4s0f0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000
    link/ether 10:60:4b:9a:bd:7c brd ff:ff:ff:ff:ff:ff
    inet6 fe80::1260:4bff:fe9a:bd7c/64 scope link valid_lft forever preferred_lft forever
3: enp4s0f1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000
    link/ether 10:60:4b:9a:bd:7d brd ff:ff:ff:ff:ff:ff
    inet6 fe80::1260:4bff:fe9a:bd7d/64 scope link valid_lft forever preferred_lft forever
4: enp4s0f2: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000
    link/ether 10:60:4b:9a:bd:7e brd ff:ff:ff:ff:ff:ff inet 10.31.100.63/23 brd 10.31.101.255 scope global dynamic enp4s0f2 valid_lft 28767sec preferred_lft 28767sec
    inet6 fe80::1260:4bff:fe9a:bd7e/64 scope link valid_lft forever preferred_lft forever

这是输出sudo netplan --debug apply

DEBUG:Merged config:
network:
  ethernets:
    enp4s0f0:
      dhcp4: false
      dhcp6: false
    enp4s0f1:
      dhcp4: false
      dhcp6: true
    enp4s0f2:
      dhcp4: true
      dhcp6: true

正如预期的那样，仅从enp4s0f2DHCP 服务器获取 IPv4。虽然enp4s0f0有dhcp6: false，但我看不出与其他两个 NIC 有什么区别。它也有 IPv6。是我读错了还是 netplan 没有按我的预期执行？

答案1

此处显示的 ipv6 地址是链路本地地址，而不是 DHCPv6 地址。要禁用链路本地地址，请设置link-local: [ ]而不是默认设置，link-local: [ ipv6 ]如手册页中所述netplan(5)。
