IPV6 冲突 VM Ubuntu 20.04 - Netplan

IPV6 冲突 VM Ubuntu 20.04 - Netplan

我遇到了一个问题,我有两个虚拟机,但问题是,当我打开第二台虚拟机时,我失去了与第一台虚拟机的连接,反之亦然。

以下是主机服务器上的桥接网络计划配置:

network:
  version: 2
  renderer: networkd
  ethernets:
    enp1s0f0:
      dhcp4: no
      dhcp6: no
  bridges:
    viifbr0:
      addresses:
        - 135.xxx.159.xx/24
        - 2001:xxxx:xxx:500f::/128
      interfaces: [ enp1s0f0 ]
      routes:
        - on-link: true
          to: 0.0.0.0/0
          via: 135.xxx.159.xxx
        - on-link: true
          to: ::0/
          via: 2001:xxxx:xxx:50ff:ff:ff:ff:ff
      gateway6: 2001:xxxx:xxx:50ff:ff:ff:ff:ff
      macaddress: xx:40:xx:fe:xx:7b
      nameservers:
         addresses:
           - 8.8.8.8
           - 8.8.4.4
           - 2001:4860:4860::8888
           - 2001:4860:4860::8844

(已启用 IPv6 转发)

以下是客户端网络配置:

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0
iface eth0 inet6 static
        accept_ra 0
        address 2001:xxxx:xxx:500f::a2
        netmask 64


post-up /sbin/ip -r route add 2001:xxxx:xxx:50ff:ff:ff:ff:ff dev eth0
post-up /sbin/ip -r route add default via 2001:xxxx:xxx:50ff:ff:ff:ff:ff

你能帮助我吗 ?

谢谢。

问候,Irkoska

确保虚拟机具有不同的 MAC 地址。外部 DHCP 服务器无法区分具有相同 MAC 地址的虚拟机,因此会为两者分配相同的 IP 地址。
