步骤如下啊
R1的配置：
Router>en
Router#en
Router#conf t
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#no ip do lo
Router(config)#line con 0
Router(config-line)#no exec-t
Router(config-line)#logg s
Router(config-line)#ho R1
R1(config)#ipv6 unicast-routing
R1(config-if)#ipv6 address 2006:bbbb::1/64
R1(config-if)#inter lo1
R1(config-if)#ipv6 address 2007:cccc::1/64
R1(config-if)#inter s2/1
R1(config-if)#ipv6 address 2008:dddd::1/64
R1(config-if)#no shut

R1#show ipv6 rou
