配置IPv6 over IPv4手动隧道示例

配置IPv6 over IPv4手动隧道示例

组网需求
如图所示，两个IPv6网络分别通过RouterA和RouterC与IPv4骨干网络中的RouterB连接，客户希望两个IPv6网络能通过IPv4骨干网互通。

配置思路
配置IPv6 over IPv4手动隧道的思路如下：
    配置物理接口的IP地址，使设备可以和IPv4骨干网进行通信。
    配置隧道接口的IPv6地址、源接口、目的地址，使设备可以和网络进行通信。
    配置协议类型为IPv6-IPv4，使IPv6网络可以通过IPv4骨干网进行通信。
操作步骤
    配置RouterA
    # 配置接口的IP地址。
    <Huawei>system-view
    [Huawei] sysname RouterA
    [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] quit
    # 配置协议类型为IPv6-IPv4。
    [RouterA] interface tunnel 0/0/1
    [RouterA-Tunnel0/0/1] tunnel-protocol ipv6-ipv4
    # 配置隧道接口的IPv6地址、源接口、目的地址。
    [RouterA-Tunnel0/0/1] ipv6 enable
    [RouterA-Tunnel0/0/1] ipv6 address 2001::1/64
    [RouterA-Tunnel0/0/1] source gigabitethernet 1/0/0
    [RouterA-Tunnel0/0/1] destination 192.168.51.2
    [RouterA-Tunnel0/0/1] quit
    # 配置静态路由。
    [RouterA] ip route-static 192.168.51.2 255.255.255.0 192.168.50.1
    配置RouterB
    # 配置接口的IP地址。
    <Huawei> system-view
    [Huawei] sysname RouterB
    [RouterB] interface gigabitethernet 1/0/0
    [RouterB-GigabitEthernet1/0/0] ip address 192.168.50.1 255.255.255.0
    [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] quit
    配置RouterC
    # 配置接口的IP地址。
    <Huawei> system-view
    [Huawei] sysname RouterC
    [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] quit
    # 配置协议类型为IPv6-IPv4。
    [RouterC] interface tunnel 0/0/1
    [RouterC-Tunnel0/0/1] tunnel-protocol ipv6-ipv4
    # 配置隧道接口的IPv6地址、源接口、目的地址。
    [RouterC-Tunnel0/0/1] ipv6 enable
    [RouterC-Tunnel0/0/1] ipv6 address 2001::2/64
    [RouterC-Tunnel0/0/1] source gigabitethernet 1/0/0
    [RouterC-Tunnel0/0/1] destination 192.168.50.2
    [RouterC-Tunnel0/0/1] quit
    # 配置静态路由。
    [RouterC] ip route-static 192.168.50.2 255.255.255.0 192.168.51.1
    验证配置结果
    # 在RouterC上Ping RouterA的接口GE1/0/0的IPv4地址，可收到返回的报文。
