第17章 IPV6路由-17.1 OSPFv3

1.OSPFv3基本配置

1）R1接口配置

[R1]ipv6 
[R1]interface GigabitEthernet 0/0/0
[R1-GigabitEthernet0/0/0]ipv6 enable 
[R1-GigabitEthernet0/0/0]ipv6 address 2001::1 64

2）R2接口配置

[R2]ipv6
[R2]interface GigabitEthernet 0/0/0
[R2-GigabitEthernet0/0/0]ipv6 enable
[R2-GigabitEthernet0/0/0]ipv6 address 2001::2 64

3）R3接口配置

[R3]ipv6
[R3]interface GigabitEthernet 0/0/0
[R3-GigabitEthernet0/0/0]ipv6 enable
[R3-GigabitEthernet0/0/0]ipv6 address 2001::3 64

4）R4接口配置

[R4]ipv6
[R4]interface GigabitEthernet 0/0/0
[R4-GigabitEthernet0/0/0]ipv6 enable
[R4-GigabitEthernet0/0/0]ipv6 address 2001::4 64

5）R1配置OSPFv3路由协议

[R1]ospfv3 
[R1-ospfv3-1]router-id 1.1.1.1
[R1]interface GigabitEthernet 0/0/0
[R1-GigabitEthernet0/0/0]ospfv3 1 area 0

6）R2配置OSPFv3路由协议

[R2]ospfv3
[R2-ospfv3-1]router-id 2.2.2.2
[R2-ospfv3-1]interface GigabitEthernet 0/0/0
[R2-GigabitEthernet0/0/0]ospfv3 1 area 0

7）R3配置OSPFv3路由协议

[R3]ospfv3
[R3-ospfv3-1]router-id 3.3.3.3
[R3-ospfv3-1]interface GigabitEthernet 0/0/0
[R3-GigabitEthernet0/0/0]ospfv3 1 area 0

8）R4配置OSPFv3路由协议

[R4]ospfv3
[R4-ospfv3-1]router-id 4.4.4.4
[R4-ospfv3-1]interface GigabitEthernet 0/0/0
[R4-GigabitEthernet0/0/0]ospfv3 1 area 0

9）R4查看邻居信息，可以看到DR优先级（缺省为1）以及邻居状态，此时R1为DR，R2为BDR。

[R4]display ospfv3 peer
OSPFv3 Process (1)
OSPFv3 Area (0.0.0.0)
Neighbor ID     Pri  State            Dead Time Interface            Instance ID
1.1.1.1           1  Full/DR          00:00:39  GE0/0/0                        0
2.2.2.2           1  Full/Backup      00:00:33  GE0/0/0                        0
3.3.3.3           1  2-Way/DROther    00:00:35  GE0/0/0                        0

10）分别修改接口的DR优先级，R4配置优先级100，R3配置DR优先级50，R2配置DR优先级0不参与选举

[R4]interface GigabitEthernet 0/0/0
[R4-GigabitEthernet0/0/0]ospfv3 dr-priority 100
[R3]interface GigabitEthernet 0/0/0
[R3-GigabitEthernet0/0/0]ospfv3 dr-priority 50
[R2]interface GigabitEthernet 0/0/0
[R2-GigabitEthernet0/0/0]ospfv3 dr-priority 0

11）在所有路由器上重启ospfv3重新选举

<R1>reset ospfv3 1
Warning: The OSPFv3 process(es) will be reset. Continue?[Y/N]y
<R2>reset ospfv3 1
Warning: The OSPFv3 process(es) will be reset. Continue?[Y/N]y
<R3>reset ospfv3 1
Warning: The OSPFv3 process(es) will be reset. Continue?[Y/N]y
<R4>reset ospfv3 1
Warning: The OSPFv3 process(es) will be reset. Continue?[Y/N]y
