需求：将两个孤立的IPV6网络通过IPV4连接起来

使用技术：IPV6隧道技术

要求：R1和R2这两台边缘路由器必须支持IPV6

R1配置如下:

Ipv6 unicast-routing #IPV6路由单播

Interface loopback 0

No ip address

Ipv6 address 2000::/64 eui-64

Ipv6 enable

Ipv6 ospf network point-to-point #指定OSPF网络类型

Ipv6 ospf 100 area 0 #将接口加入OSPF100进程，区域为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 #指定通道目标IPV4地址

Tunnel mode ipv6ip #指定通道模式为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:

Ipv6 unicast-routing

Interface loopback 0

No ip address

Ipv6 address 2001::/64 eui-64

Ipv6 enable

Ipv6 ospf network point-to-point

Ipv6 ospf 100 area 0

Interface FastEthernet 0/0

Ip addr 10.10.10.2 255.255.255.0

Duplex half

No cdp enable

#建立通道

Interface Tunnel 0

Ipv6 addr 2013:1:1:11::2/64

Ipv6 enable

Ipv6 ospf 100 area 0

Tunnel source FastEthernet 0/0

Tunnel destination 10.10.10.1

Tunnel mode ipv6ip

#IPV6 OSPF 配置

Ipv6 router ospf 100
