S2000-EA系列交换机IPv6单播地址的配置

S2000-EA系列交换机IPv6单播地址的配置

 

一、  组网需求：

两台H3C S2000-EA系列以太网交换机通过以太网端口直接相连，以太网端口属于VLAN1。分别在两台交换机上给VLAN接口1配置IPv6地址，验证它们之间的互通性。其中SwitchA的全球单播网络地址为3001::1/64，SwitchB的全球单播网络地址为3001::2/64。

二、  组网图：

三、  配置步骤：

(1)  配置SwitchA

# 配置VLAN接口1的自动链路本地地址。

<SwitchA> system-view

[SwitchA] interface Vlan-interface 1

[SwitchA-Vlan-interface1] ipv6 address auto link-local

# 配置VLAN接口1的全球单播地址。

[SwitchA-Vlan-interface1] ipv6 address 3001::1/64

(2)  配置SwitchB

# 配置VLAN接口1的自动链路本地地址。

<SwitchB> system-view

[SwitchB] interface Vlan-interface 1

[SwitchB-Vlan-interface1] ipv6 address auto link-local

# 配置VLAN接口1的全球单播地址。

[SwitchB-Vlan-interface1] ipv6 address 3001::2/64

(3)  验证配置结果

# 显示SwitchA的接口信息。

[SwitchA-Vlan-interface1] display ipv6 interface Vlan-interface 1

Vlan-interface1 current state :UP

Line protocol current state :UP

IPv6 is enabled, link-local address is FE80::20F:E2FF:FE47:4CA3

  Global unicast address(es):

    3001::1, subnet is 3001::/64

  Joined group address(es):

    FF02::1:FF47:4CA3

    FF02::1

  MTU is 1500 bytes

  ND DAD is enabled, number of DAD attempts: 1

  ND reachable time is 30000 milliseconds

  ND retransmit interval is 1000 milliseconds

  Hosts use stateless autoconfig for addresses

# 显示SwitchB的接口信息。

[SwitchB-Vlan-interface1] display ipv6 interface Vlan-interface 1

  Joined group address(es):

# 从SwitchA上分别Ping SwitchB的链路本地地址及全球单播地址。如果配置正确，则两种类型的IPv6地址都可以Ping通。

四、  配置关键点：

使用ping ipv6命令验证目的地址是否可达时，如果目的地址是链路本地地址，必须指定-i参数。
