配置IPv6 over IPv4手动隧道示例

组网需求

如图1所示，两台IPv6主机分别通过SwitchA和SwitchC与IPv4骨干网络连接，客户希望两台IPv6主机能通过IPv4骨干网互通。

配置思路

配置IPv6 over IPv4手动隧道的思路如下：

1. 配置IPv4网络。配置接口的IPv4地址和静态路由，使SwitchA、SwitchB和SwitchC三者之间路由互通。

2. 配置IPv6网络。配置隧道边界设备（SwitchA和SwitchC）的IPv6地址，使隧道边界设备与下挂的IPv6主机之间网络互通。

3. 配置IPv6 over IPv4手动隧道。配置隧道接口的IPv6地址、协议类型、源接口和目的地址，使IPv6报文可以在IPv4网络中传输。

4. 配置IPv6报文指向隧道的静态路由，从而使IPv6报文进入隧道。

做业务环回聚合的接口必须是空闲的，没有承载业务的接口。

在Eth-Trunk接口上使能业务环回功能后，加入Eth-Trunk中的物理接口就会处于UP状态，否则Tunnel接口的链路层协议将无法正常运行。

操作步骤

• SwitchA的配置文件

#
sysname SwitchA
#
ipv6
#
vlan batch 10 100
#
interface Vlanif10
 ipv6 enable
 ipv6 address FC00:1::1/64
#
interface Vlanif100
 ip address 192.168.50.2 255.255.255.0
#
interface Eth-Trunk1
 stp disable
 service type tunnel
#
interface GigabitEthernet0/0/1
 port link-type hybrid
 port hybrid pvid vlan 100
 port hybrid untagged vlan 100
#
interface GigabitEthernet0/0/2
 port link-type access
 port default vlan 10
#
interface GigabitEthernet0/0/3
 eth-trunk 1
#
interface Tunnel0/0/0
 ipv6 enable
 ipv6 address FC00:3::1/64
 tunnel-protocol ipv6-ipv4
 source Vlanif100
 destination 192.168.51.2
 eth-trunk 1
#
ip route-static 192.168.51.0 255.255.255.0 192.168.50.1
#
ipv6 route-static FC00:2:: 64 Tunnel0/0/0
#
return

• SwitchB的配置文件

#
sysname SwitchB
#
vlan batch 100 200
#
interface Vlanif100
 ip address 192.168.50.1 255.255.255.0
#
interface Vlanif200
 ip address 192.168.51.1 255.255.255.0
#
interface GigabitEthernet0/0/1
 port link-type hybrid
 port hybrid pvid vlan 100
 port hybrid untagged vlan 100
#
interface GigabitEthernet0/0/2
 port link-type hybrid
 port hybrid pvid vlan 200
 port hybrid untagged vlan 200
#
return

• SwitchC的配置文件

#
sysname SwitchC
#
ipv6
#
vlan batch 20 200
#
interface Vlanif20
 ipv6 enable
 ipv6 address FC00:2::2/64
#
interface Vlanif200
 ip address 192.168.51.2 255.255.255.0
#
interface Eth-Trunk1
 stp disable
 service type tunnel
#
interface GigabitEthernet0/0/1
 port link-type hybrid
 port hybrid pvid vlan 200
 port hybrid untagged vlan 200
#
interface GigabitEthernet0/0/2
 port link-type access
 port default vlan 20
#
interface GigabitEthernet0/0/3
 eth-trunk 1
#
interface Tunnel1
 ipv6 enable
 ipv6 address FC00:3::2/64
 tunnel-protocol ipv6-ipv4
 source Vlanif200
 destination 192.168.50.2
 eth-trunk 1
#
ip route-static 192.168.50.0 255.255.255.0 192.168.51.1
#
