配置IPV6网络

标签：ospf v3   vrrp ipv6   

1. 使用eNSP模拟器搭建试验环境（拓扑如下），

2. 核心网配置ospf v3路由协议，R2和R3配置VRRP ipv6

3. IP地址采用ipv6版本，PC机采用手动配置IPv6地址2001:DB8:C703:4416::4/64

4. 要求配置全网互通，VRRP实现冗余备份

二、 实验拓扑:

三、 IP地址规划：

四、 配置文件及步骤：

1.  R1的配置

1) IP配置

<Huawei>sy

[Huawei]sysname R1

[R1]ipv6  //开启路由器IPv6报文转发功能

[R1]int g0/0/0

[R1-GigabitEthernet0/0/0]ipv6 enable  //开启路由器接口IPv6报文转发功能

[R1-GigabitEthernet0/0/0]ipv6 address 12::1 64  //配置接口的全球单播ipv6地址

[R1-GigabitEthernet0/0/0]undo shut

[R1]int g0/0/1

[R1-GigabitEthernet0/0/1]ipv6 enable

[R1-GigabitEthernet0/0/1]ipv6 address 13::1 64

[R1-GigabitEthernet0/0/1]undo shut

[R1-GigabitEthernet0/0/1]int lo 0

[R1-LoopBack0]ipv6 enable

[R1-LoopBack0]ipv6 address 11::1 64

[R1-LoopBack0]display ipv6 int b

2) 路由配置

[R1]ospfv3  //启动OSPFv3，进入OSPFv3视图

[R1-ospfv3-1]router-id 1.1.1.1  //配置Router ID

[R1-ospfv3-1]q

[R1]int g0/0/0

[R1-GigabitEthernet0/0/0]ospfv3 1 area 0 //在接口上启用

Ospfv3，并让其属于区域0

[R1-GigabitEthernet0/0/0]int g0/0/1

[R1-GigabitEthernet0/0/1]ospfv3 1 area 0

[R1-GigabitEthernet0/0/1]int lo 0

[R1-LoopBack0]ospfv3 1 area 0

[R1-LoopBack0]q

<R1>display ospfv3 peer

<R1>display ospfv3 routing

2. R2的配置

1) IP配置

<Huawei>sy

[Huawei]sysname R2

[R2]ipv6

[R2]int g0/0/2

[R2-GigabitEthernet0/0/2]ipv6 enable

[R2-GigabitEthernet0/0/2]ipv6 address 12::2 64

[R2-GigabitEthernet0/0/2]undo shut

[R2-GigabitEthernet0/0/2]int g0/0/0

[R2-GigabitEthernet0/0/0]ipv6 enable

[R2-GigabitEthernet0/0/0]ipv6 address 23::2 64

[R2-GigabitEthernet0/0/0]undo shut

[R2-GigabitEthernet0/0/0]int g0/0/1

[R2-GigabitEthernet0/0/1]ipv6 enable

[R2-GigabitEthernet0/0/1]ipv6 address fe80::2 link-local  //手动配置接口的链路本地地址

[R2-GigabitEthernet0/0/1]undo shut

[R2-GigabitEthernet0/0/1]ipv6 addr 2001:DB8:C703:4416::2 64  //配置接口的全球单播ipv6地址

[R2-GigabitEthernet0/0/1]undo shut

[R2-GigabitEthernet0/0/1]undo ipv6 nd ra halt  //开启RA消息发布的功能，以便客户机获得路由设备的RA报文消息

[R2]display ipv6 int b

2) 路由配置

[R2]ospfv3

[R2-ospfv3-1]router-id 2.2.2.2

[R2-ospfv3-1]q

[R2]int g0/0/2

[R2-GigabitEthernet0/0/2]ospfv3 1 area 0

[R2-GigabitEthernet0/0/2]int g0/0/1

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

[R2-GigabitEthernet0/0/1]int g0/0/0

[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  //创建备份组，并配置虚拟ipv6地址（飘移地址）为链路本地地址

[R2-GigabitEthernet0/0/1]vrrp6 vrid 1 virtual-ip 2001:DB8:C703:4416::1  //创建备份组，并配置虚拟ipv6地址（飘移地址）为全球单播地址

[R2-GigabitEthernet0/0/1]vrrp6 vrid 1 priority 115  //设置优先级为115（默认是100，监听的上行口每挂一个就减10，这里要求当G0/0/2和G0/0/0都挂了的时候才被BACKUP抢占），让路由器R2成为master负责转发数据流量

[R2-GigabitEthernet0/0/1]vrrp6 vrid 1 preempt-mode timer delay 0  //设置抢占时间为0，即立即抢占，默认就是0可不输入这条命令

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

[R2-GigabitEthernet0/0/1] vrrp6 vrid 1 track int g0/0/0 //监听上行口

[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、 结果验证 :

Ping R1环回口的

跟踪路由

将R2的g0/0/2和g0/0/0都shut,先查看vrrp6的状态

再跟踪到R1环回口11：1的路由

在实验过程中曾出现master路由器R2在上行 口down且优先级比R3小的时候， vrrp状态依然是master，同时R3也是master，这就有了2个master，

原因可能是：一是延迟，二是模拟器问题
