如何在H3CS5800-32F某一VLAN启用分配的一段IPV6地址

IPv6基础典型配置举例

1. 组网需求

·     如图1-8所示，Host、Switch A和Switch B之间通过以太网端口相连，将以太网端口分别加入相应的VLAN里，在VLAN接口上配置IPv6地址，验证它们之间的互通性。

·     Switch B有可以到Host的路由。

·     在Host上安装IPv6，根据IPv6邻居发现协议自动配置IPv6地址，有可以到Switch B的路由。

2. 组网图

3. 配置步骤

(1)     配置Switch A

# 手工指定VLAN接口2的全球单播地址。

<SwitchA> system-view

[SwitchA] interface vlan-interface 2

[SwitchA-Vlan-interface2] ipv6 address 3001::1/64

[SwitchA-Vlan-interface2] quit

# 手工指定VLAN接口1的全球单播地址，并允许其发布RA消息。（缺省情况下，所有的接口不会发布RA消息）

[SwitchA] interface vlan-interface 1

[SwitchA-Vlan-interface1] ipv6 address 2001::1/64

[SwitchA-Vlan-interface1] undo ipv6 nd ra halt

[SwitchA-Vlan-interface1] quit

(2)     配置Switch B

# 配置VLAN接口2的全球单播地址。

<SwitchB> system-view

[SwitchB] interface vlan-interface 2

[SwitchB-Vlan-interface2] ipv6 address 3001::2/64

[SwitchB-Vlan-interface2] quit

# 配置IPv6静态路由，该路由的目的地址为2001::/64，下一跳地址为3001::1。

[SwitchB] ipv6 route-static 2001:: 64 3001::1

(3)     配置Host

在Host上安装IPv6，根据IPv6邻居发现协议自动配置IPv6地址。

# 从Switch A上查看端口Ten-GigabitEthernet 1/0/2的邻居信息。

[SwitchA] display ipv6 neighbors interface ten-GigabitEthernet 1/0/2

         Type: S-Static    D-Dynamic    O-Openflow    I-Invalid

IPv6 Address                 Link Layer     VID  Interface    State T Age

FE80::215:E9FF:FEA6:7D14      0015-e9a6-7d14  1     XGE1/0/2    STALE D 1238

2001::15B:E0EA:3524:E791      0015-e9a6-7d14  1     XGE1/0/2    STALE D 1248

通过上面的信息可以知道Host上获得的IPv6全球单播地址为2001::15B:E0EA:3524:E791。

4. 验证配置

# 显示Switch A的接口信息，可以看到各接口配置的IPv6全球单播地址。
