华为IPv6 6to4隧道配置

一、网络拓扑

image.png

R1-R3(Internet)-R2之间的网络为IPv4环境，PC1及PC2处于IPv6孤岛，R1及R2为IPv6/IPv4双栈设备，在R1和R2上部署6to4隧道使得PC1及PC2能够互相访问。

二、基本配置

• R1配置

display current-configuration 
[V200R003C00]
#
 sysname R1
#
ipv6 
#
interface GigabitEthernet0/0/1
 ip address 200.1.1.1 255.255.255.0 
#
interface GigabitEthernet0/0/2
 ipv6 enable 
 ipv6 address 2002:C801:101::FFFF/64 
#
interface Tunnel0/0/0
 ipv6 enable 
 ipv6 address auto link-local
 tunnel-protocol ipv6-ipv4 6to4
 source 200.1.1.1
#
ip route-static 0.0.0.0 0.0.0.0 200.1.1.2
#
ipv6 route-static 2002:C802:202:: 64 Tunnel0/0/0 
#
return
  

• R2配置

display current-configuration 
[V200R003C00]
#
 sysname R2
#
ipv6 
#
interface GigabitEthernet0/0/1
 ipv6 enable 
 ipv6 address 2002:C802:202::FFFF/64 
#
interface GigabitEthernet0/0/2
 ip address 200.2.2.2 255.255.255.0 
#
interface Tunnel0/0/0
 ipv6 enable 
 ipv6 address auto link-local
 tunnel-protocol ipv6-ipv4 6to4
 source 200.2.2.2
#
ip route-static 0.0.0.0 0.0.0.0 200.2.2.1
#
ipv6 route-static 2002:C801:101:: 64 Tunnel0/0/0 
#
return
  

• R3(Internet)配置

display current-configuration 
[V200R003C00]
#
 sysname Internet
#
interface GigabitEthernet0/0/1
 ip address 200.1.1.2 255.255.255.0 
#
interface GigabitEthernet0/0/2
 ip address 200.2.2.1 255.255.255.0 
#
return
  

• PC1设置
  IPv6地址：2002:C801:0101::1/64
  IPv6网关：2002:C801:0101::FFFF
• PC2设置
  IPv6地址：2002:C802:0202::1/64
  IPv6网关：2002:C802:0202::FFFF

三、结果验证

• R1接口状态
