R4(config-if)#ipv6 address 2001:34::4/
R4(config-if)#no sh
R4(config-if)#int f0/0
R4(config-if)#ipv6 address 4::4/
R4(config-if)#no sh
四、配置及调试过程：
1.在路由器上开启OSPFv3，并在接口上应用：
R1(config)#ipv6 router ospf 1
R1(config-rtr)#router-id 1.1.1.1
R1(config-rtr)#default-information originate metric 30 metric-type 2
R1(config-if)#int s1/0
R1(config-if)# ipv6 ospf 1 area 1
R2(config)#ipv6 router ospf 1
R2(config-rtr)#router-id 2.2.2.2
R2(config-if)#interface s1/1
R2(config-if)#ipv6 ospf 1 a 0
R2(config-if)#int s1/0
R2(config-if)#ipv6 ospf 1 a 1
R3(config)#ipv6 router ospf 1
R3(config-rtr)#router-id 3.3.3.3
R3(config-if)#int s1/0
R3(config-if)#ipv6 ospf 1 a 2
R3(config-if)#int s1/1
R3(config-if)#ipv6 ospf 1 a 0
R4(config)#ipv6 router ospf 1
R4(config-rtr)#router-id 4.4.4.4
R4(config-if)#int s1/0
R4(config-if)#ip ospf 1 area 2
R4(config-if)#int f0/0
R4(config-if)#ipv6 ospf 1 area 2
2.测试网络连通性：
R4(config-if)#do ping 1::1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 1::1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 24/44/68 ms
已通！
3.在R4上查看IPv6路由表：
R4(config-if)#do sh ipv6 route
IPv6 Routing Table - 6 entries
Codes: C - Connected, L - Local, S - Static, R - RIP, B - BGP
U - Per-user Static route, M - MIPv6
I1 - ISIS L1, I2 - ISIS L2, IA - ISIS interarea, IS - ISIS summary
O - OSPF intra, OI - OSPF inter, OE1 - OSPF ext 1, OE2 - OSPF ext 2
ON1 - OSPF NSSA ext 1, ON2 - OSPF NSSA ext 2
D - EIGRP, EX - EIGRP external
OE2 ::/0 [110/30], tag 1
via FE80::C802:11FF:FE34:0, Serial1/0
OI 2001:12::/ [110/192]
via FE80::C802:11FF:FE34:0, Serial1/0
OI 2001:23::/ [110/128]
via FE80::C802:11FF:FE34:0, Serial1/0
C 2001:34::/ [0/0]
via ::, Serial1/0
L 2001:34::4/128 [0/0]
via ::, Serial1/0
L FF00::/8 [0/0]
via ::, Null0
以上输出说明，路由器已通过OSPFv3协议学习到了三条路由，而且学到了R1上的默认路由，代码为OE2。区间路由为OI，区域内路由为OE2。
4.查看运行的IPv6协议：
R2(config-if)#do sh ipv pro
IPv6 Routing Protocol is "connected"
IPv6 Routing Protocol is "static"
IPv6 Routing Protocol is "ospf 1" //启动了OSPFv3协议
Interfaces (Area 0):
Serial1/1 //S1/1口属于Area0
Interfaces (Area 1):
Serial1/0 //S1/0口属于Area1
Redistribution:
None
5.查看OSPFv3数据库：
R3(config-if)#do sh ipv6 ospf database

通过以上实验可以知道，OSPFv3和OSPFv2非常相似，只是配置略有不同，但原理都是一样的。下载本文
