做tunnel:
R2#conf t
Enter configuration commands, one per line.End with CNTL/Z.
R2(config)#interface tunnel 2
R2(config-if)#
*Mar1 00:13:18.603: %LINEPROTO-5-UPDOWN: Line protocol on Interface Tunnel2, changed state to down
R2(config-if)#tunnel source 2.2.2.2 //源地址自己的环回口
R2(config-if)#tunnel destination 3.3.3.3//目的地址R3的环回口地址
R2(config-if)#tunnel mode ipv6ip //把IPv6转成IPv4
R2(config-if)#ipv6 enable //给IPV6地址
R2(config-if)# rip：只宣告tunnel接口和以太口
R2#conf t
Enter configuration commands, one per line.End with CNTL/Z.
R2(config)#ipv6 unicast-routing
R2(config)#ipv6 router rip A
R2(config-rtr)#exit
R2(config)#interface tunnel 2
R2(config-if)#ipv6 rip A enable
R2(config-if)#exit
R2(config)#interface ethernet 1/0
R2(config-if)#ipv6 rip A enable
R2(config-if)#
