查看有关 HSRP IPv6 配置的 Cisco 文档，我注意到使用了“standby 1 ipv6 autoconfig”。

interface FastEthernet0/0
 no ip address
 duplex auto
 speed auto
 ipv6 address 2020:AB8:2001::1011/64
 ipv6 enable
 standby version 2
 standby 1 ipv6 autoconfig
 standby 1 preempt delay minimum 30
 standby 1 track Serial0/0

在我的设置中，我决定为虚拟 IP 使用手动配置的 IPv6 地址。为什么我不应该使用静态虚拟地址而不是自动配置？

 interface GigabitEthernet0/2
  no ip address
  standby version 2
  standby 1 ipv6 2001:DB8:1:23::1/64
  standby 1 priority 110
  standby 1 preempt delay minimum 10
  duplex auto
  speed auto
  media-type rj45
  ipv6 address 2001:DB8:1:23::2/64
  ipv6 ospf 1 area 23
 end


interface GigabitEthernet0/2
  no ip address
  standby version 2
  standby 1 ipv6 2001:DB8:1:23::1/64
  duplex auto
  speed auto
  media-type rj45
  ipv6 address 2001:DB8:1:23::3/64
  ipv6 ospf 1 area 23
end
