华为三层交换机做OSPF

配置OSPF基本功能

组网需求

如图1所示，所有的S9300都运行OSPF，并将整个自治系统划分为3个区域，其中S9300-A和S9300-B作为ABR来转发区域之间的路由。

配置完成后，每台S9300都应学到自治系统的到所有网段的路由。

图1 OSPF基本配置组网图

S9300 接口对应的VLANIF IP地址

S9300-A GigabitEthernet1/0/1 VLANIF 10 192.168.0.1/24

S9300-A GigabitEthernet1/0/2 VLANIF 20 192.168.1.1/24

S9300-B GigabitEthernet1/0/1 VLANIF 10 192.168.0.2/24

S9300-B GigabitEthernet1/0/2 VLANIF 30 192.168.2.1/24

S9300-C GigabitEthernet1/0/1 VLANIF 20 192.168.1.2/24

S9300-C GigabitEthernet1/0/2 VLANIF 40 172.16.1.1/24

S9300-D GigabitEthernet1/0/1 VLANIF 30 192.168.2.2/24

S9300-D GigabitEthernet1/0/2 VLANIF 50 172.17.1.1/24

配置思路

采用如下的思路配置OSPF基本功能：

1.配置各接口所属VLAN ID。

2.配置各VLANIF接口的IP地址。

3.在各S9300设备上使能OSPF，指定不同区域的网段。

4.查看路由表及数据库信息。

数据准备

?各接口所属的VLAN ID，具体数据如图1所示。

?各VLANIF接口的IP地址，具体数据如图1所示。

?各S9300设备的Router ID，OSPF进程号以及各接口所属的区域。

?S9300-A的Router ID 1.1.1.1，运行的OSPF进程号1，在区域0的网段192.168.0.0/24，在区域1的网段192.168.1.0/24。

?S9300-B的Router ID 2.2.2.2，运行的OSPF进程号1，在区域0的网段192.168.0.0/24，在区域2的网段192.168.2.0/24。

?S9300-C的Router ID 3.3.3.3，运行的OSPF进程号1，在区域1的网段192.168.1.0/24，172.16.1.0/24。

?S9300-D的Router ID 4.4.4.4，运行的OSPF进程号1，在区域2的网段192.168.2.0/24，172.17.1.0/24。

?S9300-E的Router ID 5.5.5.5，运行的OSPF进程号1，在区域1的网段172.16.1.0/24。

?S9300-F的Router ID 6.6.6.6，运行的OSPF进程号1，在区域2的网段172.17.1.0/24。

操作步骤

1.配置各接口所属VLAN

S9300-B、S9300-C、S9300-D、S9300-E、S9300-F上的配置同S9300-A(略)

13.配置各VLANIF接口的IP地址

14.[S9300-A] interface vlanif 10

15.[S9300-A-Vlanif10] ip address 192.168.0.1 24
