H3C S3500

欢迎您访问我爱IT技术网，今天小编为你分享的电脑教程是网络协议方面的经验知识教程：H3C S3500，下面是详细的分享！

H3C S3500

一、 组网需求：

所有的交换机都运行OSPF，并将整个自治系统划分为3个区域。

其中Switch A和Switch B作为ABR来转发区域之间的路由。

配置完成后，每台交换机都应学到AS内的到所有网段的路由。

二、 组网图：

三、 配置步骤：

(1) 配置各接口的IP地址(此处略)

(2) 配置OSPF基本配置

# 配置Switch A。

system-view

[SwitchA] ospf

[SwitchA-ospf-1] area 0

[SwitchA-ospf-1-area-0.0.0.0] network 192.168.0.0 0.0.0.255

[SwitchA-ospf-1-area-0.0.0.0] quit

[SwitchA-ospf-1] area 1

[SwitchA-ospf-1-area-0.0.0.1] network 192.168.1.0 0.0.0.255

[SwitchA-ospf-1-area-0.0.0.1] quit

[SwitchA-ospf-1] quit

# 配置Switch B。

system-view

[SwitchB] ospf

[SwitchB-ospf-1] area 0

[SwitchB-ospf-1-area-0.0.0.0] network 192.168.0.0 0.0.0.255

[SwitchB-ospf-1-area-0.0.0.0] quit

[SwitchB-ospf-1] area 2

[SwitchB-ospf-1-area-0.0.0.2] network 192.168.2.0 0.0.0.255

[SwitchB-ospf-1-area-0.0.0.2] quit

[SwitchB-ospf-1] quit

# 配置Switch C。

system-view

[SwitchC] ospf

[SwitchC-ospf-1] area 1

[SwitchC-ospf-1-area-0.0.0.1] network 192.168.1.0 0.0.0.255

[SwitchC-ospf-1-area-0.0.0.1] network 172.16.1.0 0.0.0.255

[SwitchC-ospf-1-area-0.0.0.1] quit

[SwitchC-ospf-1] quit

# 配置Switch D。

system-view

[SwitchD] ospf

[SwitchD-ospf-1] area 2

[SwitchD-ospf-1-area-0.0.0.2] network 192.168.2.0 0.0.0.255

[SwitchD-ospf-1-area-0.0.0.2] network 172.17.1.0 0.0.0.255

[SwitchD-ospf-1-area-0.0.0.2] quit

[SwitchD-ospf-1] quit

(3) 检查配置结果

# 查看Switch A的OSPF邻居。

[SwitchA] display ospf peer verbose
