需求：將兩個孤立的IPV6網絡通過IPV4連接起來
使用技術：IPV6隧道技術
要求：R1和R2這兩臺邊緣路由器必須支持IPV6
R1配置如下:
Ipv6 unicast-routing #IPV6路由單播
Interface loopback 0
No ip address
Ipv6 address 2000::/64 eui-64
Ipv6 enable
Ipv6 ospf network point-to-point #指定OSPF網絡類型
Ipv6 ospf 100 area 0 #將接口加入OSPF100進程，區域爲0
Interface FastEthernet 0/0
Ip addr 10.10.10.1 255.255.255.0
Duplex half
No cdp enable
#建立通道
Interface Tunnel 0
Ipv6 addr 2013:1:1:11::1/64
Ipv6 enable
Ipv6 ospf 100 area 0
Tunnel source FastEthernet 0/0 #指定通道源接口
Tunnel destination 10.10.10.2 #指定通道目標IPV4地址
Tunnel mode ipv6ip #指定通道模式爲IPV6IP,即Manual
#IPV6 OSPF 配置
Ipv6 router ospf 100
Router-id 1.1.1.1
log-addjacency-changes
R2配置如下:
