最佳答案
1.12 IPv6基础典型配置举例
1. 组网需求
· 如图1-10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
图1-10 IPv6地址配置组网图
交换机上已经创建相应的VLAN接口。
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GigabitEthernet1/0/2的邻居信息。
[SwitchA] display ipv6 neighbors interface gigabitethernet 1/0/2
Type: S-Static D-Dynamic O-Openflow R-Rule IS-Invalid static
IPv6 address MAC address VID Interface State T Aging
FE80::215:E9FF:FEA6:7D14 0015-e9a6-7d14 1 GE1/0/2 STALE D 1238
2001::15B:E0EA:3524:E791 0015-e9a6-7d14 1 GE1/0/2 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。

# 在Host上使用Ping测试和Switch A及Switch B的互通性；在Switch B上使用Ping测试和Switch A及Host的互通性。
在Ping链路本地地址时，需要使用-i参数来指定链路本地地址的接口。
[SwitchB] ping ipv6 -c 1 3001::1
Ping6(56 data bytes) 3001::2 --> 3001::1, press CTRL_C to break
56 bytes from 3001::1, icmp_seq=0 hlim=64 time=4.404 ms
--- Ping6 statistics for 3001::1 ---
1 packet(s) transmitted, 1 packet(s) received, 0.0% packet loss
round-trip min/avg/max/std-dev = 4.404/4.404/4.404/0.000 ms
[SwitchB] ping ipv6 -c 1 2001::15B:E0EA:3524:E791
Ping6(56 data bytes) 3001::2 --> 2001::15B:E0EA:3524:E791, press CTRL_C to break
56 bytes from 2001::15B:E0EA:3524:E791, icmp_seq=0 hlim=64 time=5.404 ms
--- Ping6 statistics for 2001::15B:E0EA:3524:E791 ---

round-trip min/avg/max/std-dev = 5.404/5.404/5.404/0.000 ms
从Host上也可以ping通Switch B和Switch A，证明它们是互通的。
