1. 使用eNSP模擬器搭建試驗環境（拓撲如下），

2. 核心網配置ospf v3路由協議，R2和R3配置VRRP ipv6

3. IP地址采用ipv6版本，PC機采用手動配置IPv6地址2001:DB8:C703:4416::4/64

4. 要求配置全網互通，VRRP實現冗余備份

二、 實驗拓撲:

三、 IP地址規劃：

四、 配置文件及步驟：

1. R1的配置

[R2-GigabitEthernet0/0/0]ospfv3 1 area 0

[R2-GigabitEthernet0/0/0]q

[R2]display ospfv3 peer

[R2]display ospfv3 routing

3) 做ipv6 vrrp

[R2]int g0/0/1

[R2-GigabitEthernet0/0/1]vrrp6 vrid 1 virtual-ip fe80::1 link-local //創建備份組，並配置虛擬ipv6地址（飄移地址）為鏈路本地地址

[R2-GigabitEthernet0/0/1]vrrp6 vrid 1 virtual-ip 2001:DB8:C703:4416::1 //創建備份組，並配置虛擬ipv6地址（飄移地址）為全球單播地址

[R2-GigabitEthernet0/0/1]vrrp6 vrid 1 priority 115 //設置優先級為115（默認是100，監聽的上行口每掛一個就減10，這裏要求當G0/0/2和G0/0/0都掛了的時候才被BACKUP搶占），讓路由器R2成為master負責轉發數據流量

[R2-GigabitEthernet0/0/1]vrrp6 vrid 1 preempt-mode timer delay 0 //設置搶占時間為0，即立即搶占，默認就是0可不輸入這條命令

[R2-GigabitEthernet0/0/1] vrrp6 vrid 1 track int g0/0/2 //監聽上行口

[R2-GigabitEthernet0/0/1] vrrp6 vrid 1 track int g0/0/0 //監聽上行口

[R2]display vrrp6 b

3. R3的配置

1) IP配置

<Huawei>sy

[Huawei]sysname R3

[R3]ipv6

[R3]int g0/0/2

[R3-GigabitEthernet0/0/2]ipv6 enable

[R3-GigabitEthernet0/0/2]ipv6 address 13::3 64

[R3-GigabitEthernet0/0/2]undo shut

[R3-GigabitEthernet0/0/2]q

[R3]int g0/0/0

[R3-GigabitEthernet0/0/0]ipv6 enable

[R3-GigabitEthernet0/0/0]ipv6 address 23::3 64

[R3-GigabitEthernet0/0/0]undo shut

[R3]int g0/0/1

[R3-GigabitEthernet0/0/1]ipv6 enable

[R3-GigabitEthernet0/0/1]ipv6 address fe80::3 link-local

[R3-GigabitEthernet0/0/1]ipv6 addr 2001:DB8:C703:4416::3 64

[R3-GigabitEthernet0/0/1]undo shut

[R3-GigabitEthernet0/0/1]undo ipv6 nd ra halt

[R3]display ipv6 int b

2) 路由配置

[R3]ipv6

[R3]ospfv3

[R3-ospfv3-1]router

[R3-ospfv3-1]router-id 3.3.3.3

[R3-ospfv3-1]q

[R3]int g0/0/2

[R3-GigabitEthernet0/0/2]ospfv3 1 a

[R3-GigabitEthernet0/0/2]ospfv3 1 area 0

[R3-GigabitEthernet0/0/2]int g0/0/1

[R3-GigabitEthernet0/0/1]ospfv3 1 area 0

[R3-GigabitEthernet0/0/1]int g0/0/0

[R3-GigabitEthernet0/0/0]ospfv3 1 area 0

[R3-GigabitEthernet0/0/0]q

[R3]display ospfv3 peer

[R3]display ospfv3 routing

3) 做ipv6 vrrp

[R3]int g0/0/1

[R3-GigabitEthernet0/0/1]vrrp6 vrid 1 virtual-ip fe80::1 link-local

[R3-GigabitEthernet0/0/1]vrrp6 vrid 1 virtual-ip 2001:DB8:C703:4416::1

[R3-GigabitEthernet0/0/1]vrrp6 vrid 1 preempt-mode timer delay 0

[R3]display vrrp6 b

五、 結果驗證 :

Ping R1環回口的

跟蹤路由

將R2的g0/0/2和g0/0/0都shut,先查看vrrp6的狀態

再跟蹤到R1環回口11：1的路由

在實驗過程中曾出現master路由器R2在上行 口down且優先級比R3小的時候， vrrp狀態依然是master，同時R3也是master，這就有了2個master，

原因可能是：一是延遲，二是模擬器問題
