一、实验拓扑：
二、实验要求：
1、R1、R2分别在接口下启用：IPv6功能；
2、通过show IPv6 int f0/0，查看：本地链路地址；
3、R1、R2分别配置EUI/64的自动填充地址；并配多个地址进行Ping试验;
4、验证:对比接口MAC地址，本地链路地址和MAC地址的关系是否在中间插入了FF:FE？
5、验证：本地链路地址第7位是否进行了置位：1变0,0变1？
6、验证：R1是否可以PingR2的本地链路地址？
7、验证：查看EUI/64自动填充地址格式？
三、命令部署：
R1(config)#int f0/0
R1(config-if)#no shutdown
R1(config-if)#ipv6 enable
R2(config)#int f0/0
R2(config-if)#no shutdown
R2(config-if)#ipv6 enable
R1#show ipv6 interface f0/0
R2#show ipv6 int f0/0
R1(config)#int f0/0
R1(config-if)#ipv6 address 2001:12:1:1::/64 eui-64
R1(config-if)#ipv6 add 2001:12:1:1::1/64
R2(config)#int f0/0
R2(config-if)#ipv6 address 2001:12:1:1::/64 eui-64
R2(config-if)#ipv6 add 2001:12:1:1::2/64
R1#show ipv6 int bri
四、验证：
R1#show ipv6 interface f0/0
FastEthernet0/0 is up, line protocol is up
IPv6 is enabled, link-local address is FE80::C801:D7FF:FE2C:0
R1#show int f0/0
FastEthernet0/0 is up, line protocol is up
Hardware is DEC21140, address is ca01.d72c.0000 (bia ca01.d72c.0000)
R1#ping FE80::C802:D7FF:FE90:0
