交换机

组网需求

如图1所示，SwitchA和SwitchB分别通过10GE1/0/1相连，两台交换机的10GE1/0/1均对应各自的VLANIF100接口，为VLANIF100接口配置IPv6全球单播地址，实现SwitchA和SwitchB互通。

配置思路

配置IPv6基础功能思路如下：

交换机接口上使能IPv6功能。
配置接口的IPv6全球单播地址。

操作步骤

创建VLAN，并将接口加入到VLAN中

# 配置SwitchA。

<HUAWEI> system-view
[~HUAWEI] sysname SwitchA
[*HUAWEI] commit
[~SwitchA] vlan batch 100
[*SwitchA] interface 10ge 1/0/1
[*SwitchA-10GE1/0/1] port link-type trunk
[*SwitchA-10GE1/0/1] port trunk allow-pass vlan 100
[*SwitchA-10GE1/0/1] quit
[*SwitchA] commit

# 配置SwitchB。

<HUAWEI> system-view
[~HUAWEI] sysname SwitchB
[*HUAWEI] commit
[~SwitchB] vlan batch 100
[*SwitchB] interface 10ge 1/0/1
[*SwitchB-10GE1/0/1] port link-type trunk
[*SwitchB-10GE1/0/1] port trunk allow-pass vlan 100
[*SwitchB-10GE1/0/1] quit
[*SwitchB] commit

接口上使能IPv6功能，并配置接口的全球单播地址

# 配置SwitchA。

[~SwitchA] interface vlanif 100
[*SwitchA-Vlanif100] ipv6 enable
[*SwitchA-Vlanif100] ipv6 address fc00:1::1/64
[*SwitchA-Vlanif100] commit
[~SwitchA-Vlanif100] quit
[~SwitchA] quit

# 配置SwitchB。

[~SwitchB] interface vlanif 100
[*SwitchB-Vlanif100] ipv6 enable
[*SwitchB-Vlanif100] ipv6 address fc00:1::2/64
[*SwitchB-Vlanif100] commit
[~SwitchB-Vlanif100] quit
[~SwitchB] quit

验证配置结果

如果配置成功，可以查看配置的全球单播地址，以及接口状态为Up，IPv6协议状态为Up，并可以查看接口的邻居情况。

# 查看SwitchA的接口信息。

<SwitchA> display ipv6 interface vlanif 100
Vlanif100 current state : UP
IPv6 protocol current state : UP
IPv6 is enabled, link-local address is FE80::C964:0:B8B6:1
  Global unicast address(es):
    FC00:1::1, subnet is FC00:1::/64
  Joined group address(es):
    FF02::1:FF00:1
    FF02::1:FFB6:1
    FF02::2
    FF02::1
  MTU is 1500 bytes
  ND DAD is enabled, number of DAD attempts: 1
  ND reachable time is 1200000 milliseconds
  ND retransmit interval is 1000 milliseconds
  Hosts use stateless autoconfig for addresses

# 查看SwitchB的接口信息。

<SwitchB> display ipv6 interface vlanif 100
Vlanif100 current state : UP
IPv6 protocol current state : UP
IPv6 is enabled, link-local address is FE80::2D6F:0:7AF3:1
  Global unicast address(es):
    FC00:1::2, subnet is FC00:1::/64
  Joined group address(es):
    FF02::1:FF00:2
    FF02::1:FFF3:1
    FF02::2
    FF02::1
  MTU is 1500 bytes
  ND DAD is enabled, number of DAD attempts: 1
  ND reachable time is 1200000 milliseconds
  ND retransmit interval is 1000 milliseconds

# 从SwitchA上可以Ping通SwitchB的链路本地地址，注意需要使用-i参数，来指定链路本地地址的接口。
