S3610_S5510系列交换机IPv6路由协议OSPFv3的DR配置

S3610_S5510系列交换机IPv6路由协议OSPFv3 DR的配置

一      组网需求：

1．Switch A的优先级为100，它是网络上的最高优先级，被选为DR；

2．Switch C的优先级为2，它是优先级第二高的，被选为BDR；

3．Switch B的优先级为0，这意味着它将无法成为DR；

4．Switch D没有配置优先级，取缺省值1。

二      组网图：

三      配置步骤：

1．配置SwitchA，启动OSPFv3，并设置其Switch ID为1.1.1.1

<SwitchA> system-view

[SwitchA] switch-mode dual-ipv4-ipv6

[SwitchA] ipv6

[SwitchA] ospfv3

[SwitchA-ospfv3-1] router-id 1.1.1.1

[SwitchA-ospfv3-1] quit

[SwitchA] interface Vlan-interface 100

[SwitchA-Vlan-interface100] ospfv3 1 area 0

[SwitchA-Vlan-interface100] quit

2．配置SwitchB，启动OSPFv3，并设置其Switch ID为2.2.2.2

<SwitchB> system-view

[SwitchB] switch-mode dual-ipv4-ipv6

[SwitchB] ipv6

[SwitchB] ospfv3

[SwitchB-ospfv3-1] router-id 2.2.2.2

[SwitchB-ospfv3-1] quit

[SwitchB] interface Vlan-interface 200

[SwitchB-Vlan-interface200] ospfv3 1 area 0

[SwitchB-Vlan-interface200] quit

3．配置SwitchC，启动OSPFv3，并设置其Switch ID为3.3.3.3

<SwitchC> system-view

[SwitchC] switch-mode dual-ipv4-ipv6

[SwitchC] ipv6

[SwitchC] ospfv3

[SwitchC-ospfv3-1] router-id 3.3.3.3

[SwitchC-ospfv3-1] quit

[SwitchC] interface Vlan-interface 100

[SwitchC-Vlan-interface100] ospfv3 1 area 0

[SwitchC-Vlan-interface100] quit

4．配置SwitchD，启动OSPFv3，并设置其Switch ID为4.4.4.4

<SwitchD> system-view

[SwitchD] switch-mode dual-ipv4-ipv6

[SwitchD] ipv6

[SwitchD] ospfv3

[SwitchD-ospfv3-1] router-id 4.4.4.4

[SwitchD-ospfv3-1] quit

[SwitchD] interface Vlan-interface 200

[SwitchD-Vlan-interface200] ospfv3 1 area 0

[SwitchD-Vlan-interface200] quit

5．配置SwitchA的接口Vlan-interface100的DR优先级为100。

[SwitchA] interface Vlan-interface 100

[SwitchA-Vlan-interface100] ospfv3 dr-priority 100

[SwitchA-Vlan-interface100] quit

6．配置SwitchB的接口Vlan-interface200的DR优先级为0。

[SwitchB] interface Vlan-interface 200

[SwitchB-Vlan-interface200] ospfv3 dr-priority 0

[SwitchB-Vlan-interface200] quit

7．配置SwitchC的接口Vlan-interface100的DR优先级为2。

[SwitchC] interface Vlan-interface 100

[SwitchC-Vlan-interface100] ospfv3 dr-priority 2

[SwitchC-Vlan-interface100] quit

8．重新进行DR/BDR选择

将所有接口一次shutdown和undo shutdown，使OSPFv3重新进行DR/BDR的选择。

四      配置关键点：

1．路由器接口的DR优先级将影响接口在选举DR时所具有的资格，优先级为0的路由器不会被选举为DR或BDR。
