R1(config-rtr)#router-id 1.1.1 .1 //定义路由器ID
R1(config-rtr)#default-information originate metric 30 metric-type 2 //向OSPFv3网络注入一条默认路由
R1(config)#interface Serial0/0
R1(config-if)#ipv6 address 2007:16::1/64
R1(config-if)#ipv6 ospf 1 area 1 //在接口上启用OSPFv3，并声明接口所在区域
R1(config-if)#no shutdown
R1(config)#ipv6 route ::/0 s0/1 //配置默认路由

4.实验调试
（1）show ipv6 route
R3#show ipv6 route
IPv6 Routing Table - 11 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:AFF:FE90:0, Serial0/0
OI 2007:16::/64 [110/192]
via FE80::C802:AFF:FE90:0, Serial0/0
OI 2007:26::/64 [110/128]
via FE80::C802:AFF:FE90:0, Serial0/0
C 2007:23::/64 [0/0]
via ::, Serial0/0/0
L 2007:23::3/128 [0/0]
via ::, Serial0/0/0
C 2008:3333::/64 [0/0]
via ::, loopback 0
L 2008:3333::3/128 [0/0]
via ::,loopback 0
L FE80::/10 [0/0]
via ::, Null0
L FF00::/8 [0/0]
via ::, Null0
以上输出表明 OSPFv3 的外部路由代码为“OE2”或“OE1”，区域间路由代码为“OI”，
区域内路由代码为“O”。
（2）show ip protocols
R6#show ipv6 protocols
IPv6 Routing Protocol is "connected"
IPv6 Routing Protocol is "static"
IPv6 Routing Protocol is "ospf 1"
Interfaces (Area 0):
Serial0/1
Interfaces (Area 1):
Serial0/0
Redistribution:
None
以上输出表明启动的 OSPFv3 进程 ID 为 1， Serial0/1 和 Serial0/0 接口上启用
OSPFv3，Serial0/1 属于区域 0，Serial0/0 属于区域 1。
（3）show ipv6 ospf database
该命令用来查看 OSPFv3拓扑结构数据库。
R3#show ipv6 ospf database

以上输出显示了路由器 R3 的OSPFv3的拓扑结构数据库。
（4）show ipv6 ospf neighbor
R6#show ipv6 ospf neighbor
Neighbor ID Pri State Dead Time Interface ID Interface
2.2.2 .2 1 FULL/ - 00:00:30 5 Serial0/1
1.1.1 .1 1 FULL/ - 00:00:37 4 Serial0/0
以上输出表明路由器 R6有两个 OSPFv3 的邻居。
（5）show ipv6 ospf interface
R6#show ipv6 ospf interface s0/0
Serial0/0 is up, line protocol is up
Link Local Address FE80::C801:AFF:FE90:0, Interface ID 4
Area 1, Process ID 1, Instance ID 0, Router ID 6.6.6 .6
Network Type POINT_TO_POINT, Cost: 64
Transmit Delay is 1 sec, State POINT_TO_POINT,
Timer intervals configured, Hello 10, Dead 40, Wait 40, Retransmit 5
Hello due in 00:00:04
Index 1/1/1 , flood queue length 0
Next 0x0(0)/0x0(0)/0x0(0)
Last flood scan length is 1, maximum is 1
Last flood scan time is 0 msec, maximum is 0 msec
Neighbor Count is 1, Adjacent neighbor count is 1
Adjacent with neighbor 1.1.1 .1

以上输出是 OSPFv3 路由器接口的基本信息，和 OSPFv2 非常的相似，包括路由器 ID、
网络类型、计时器的值以及邻居的数量等信息。
