配置IPv6 over IPv4手动隧道示例

配置IPv6 over IPv4手动隧道示例

本举例介绍IPv6 over IPv4手动隧道的配置过程。

组网需求

如图1所示，两个IPv6网络分别通过RouterA和RouterC与IPv4骨干网络中的RouterB连接，要求在RouterA和RouterC之间配置IPv6 over IPv4手动隧道，使两个IPv6网络可以互通。

说明：

在实际的组网环境中，为保证报文的正常转发，建议隧道的源接口地址指定为本端设备LoopBack 接口的IP地址（或源接口指定为本端设备的LoopBack接口），目的地址指定为对端设备LoopBack 接口的IP地址。

配置思路

配置IPv6 over IPv4手动隧道的思路如下：

1.配置物理接口的IP地址

2.配置隧道接口的IPv6地址、源接口、目的地址

3.配置协议类型为IPv6-IPv4

数据准备

为完成此配置例，需准备如下的数据：

∙接口的IP地址

∙隧道的IPv6地址、源接口和目的地址

操作步骤

1.配置RouterA

# 配置接口的IP地址。

system-view

[HUAWEI]sysnameRouterA

[RouterA] ipv6

[RouterA] interface gigabitethernet 1/0/0

[RouterA-GigabitEthernet1/0/0]ip address 192.168.50.2 255.255.255.0

[RouterA-GigabitEthernet1/0/0] undo shutdown

[RouterA-GigabitEthernet1/0/0] quit

# 配置协议类型为IPv6-IPv4。

[RouterA] interface tunnel 1/0/0

[RouterA-Tunnel1/0/0] tunnel-protocol ipv6-ipv4

# 配置隧道接口的IPv6地址、源接口、目的地址。

[RouterA-Tunnel1/0/0] ipv6 enable

[RouterA-Tunnel1/0/0] ipv6 address 3001::1/64

[RouterA-Tunnel1/0/0] source 192.168.50.2

[RouterA-Tunnel1/0/0] destination 192.168.51.2

[RouterA-Tunnel1/0/0] quit

# 配置静态路由。

[RouterA]ip route-static 192.168.51.2 255.255.255.0 192.168.50.1

2.配置RouterB

# 配置接口的IP地址。

system-view

[HUAWEI]sysnameRouterB

[RouterB] interface gigabitethernet 1/0/0

[RouterB-GigabitEthernet1/0/0]ip address 192.168.50.1 255.255.255.0 [RouterB-GigabitEthernet1/0/0] undo shutdown

[RouterB-GigabitEthernet1/0/0] quit

[RouterB] interface gigabitethernet 2/0/0

[RouterB-GigabitEthernet2/0/0]ip address 192.168.51.1 255.255.255.0 [RouterB-GigabitEthernet2/0/0] undo shutdown

[RouterB-GigabitEthernet2/0/0] quit

3.配置RouterC

# 配置接口的IP地址。

system-view

[HUAWEI]sysnameRouterC

[RouterC] ipv6

[RouterC] interface gigabitethernet 1/0/0

[RouterC-GigabitEthernet1/0/0]ip address 192.168.51.2 255.255.255.0 [RouterC-GigabitEthernet1/0/0] undo shutdown

[RouterC-GigabitEthernet1/0/0] quit

# 配置协议类型为IPv6-IPv4。

[RouterC] interface tunnel 1/0/0

[RouterC-Tunnel1/0/0] tunnel-protocol ipv6-ipv4

# 配置隧道接口的IPv6地址、源接口、目的地址。

[RouterC-Tunnel1/0/0] ipv6 enable

[RouterC-Tunnel1/0/0] ipv6 address 3001::2/64

[RouterC-Tunnel1/0/0] source 192.168.51.2

[RouterC-Tunnel1/0/0] destination 192.168.50.2

[RouterC-Tunnel1/0/0] quit

# 配置静态路由。

[RouterC]ip route-static 192.168.50.2 255.255.255.0 192.168.51.1

4.检查配置结果

# 在RouterC上Ping RouterA的接口GE1/0/0的IPv4地址，可收到返回的报文。

[RouterC] ping 192.168.50.2
