一、实验目标

续上一篇实验文章，本次实验也是通过配置实现VLAN间的路由。而上篇实验是通过配置单臂路由实现VLAN间通信，本次实验将通过配置三层交换的方式实现VLAN间的通信。

掌握配置三层交换机实现VLAN间通信的方法；
掌握以太网Trunk链路实现VLAN间通信的方法;
掌握在不同VLAN间配置动态路由协议OSPF的方法

二、实验拓扑

三、场景需求

在企业网络中，通过使用三层交换机可以简便的实现VLAN间通信。作为企业的网络管理员，需要在三层交换机配置VLANIF接口的三层功能，使得如上所示拓扑图中的网络能够实现VLAN间通信。此外，为了使S1和S2所连接的不同网络能够进行三层通信，还需要配置路由协议。

四、基本配置

配置R1&R2接口IP地址:

R1:

<Huawei>system-view 
Enter system view, return user view with Ctrl+Z.
[Huawei]sysname R1
[R1]inter g0/0/0
[R1-GigabitEthernet0/0/0]ip address 10.0.3.1 24

八、路由配置

本实验中，R1、R2、S3和S4模拟客户端主机，四台设备都需要配置一个用户IP地址，其中S3和S4使用VLANIF1接口配置IP地址, 最后为每台设备配置一条缺省静态路由指向网关:

R1:

[R1]ip route-static 0.0.0.0 0 10.0.3.254
[R1]

R2:

[R2]ip route-static 0.0.0.0 0 10.0.4.254
[R2]

S3:

[Huawei]sysname S3	
[S3]interface Vlanif 1
May 27 2022 18:40:52-08:00 S3 DS/4/DATASYNC_CFGCHANGE:OID 1.3.6.1.4.1.2011.5.25.
191.3.1 configurations have been changed. The current change number is 4, the ch

May 27 2022 18:41:26-08:00 S3 %%01IFNET/4/LINK_STATE(l)[0]:The line protocol IP 
on the interface Vlanif1 has entered the UP state.
May 27 2022 18:41:32-08:00 S3 DS/4/DATASYNC_CFGCHANGE:OID 1.3.6.1.4.1.2011.5.25.
191.3.1 configurations have been changed. The current change number is 5, the ch
ange loop count is 0, and the maximum number of records is 4095.	
[S3-Vlanif1]q
[S3]	
[S3]ip route-static 0.0.0.0 0 10.0.2.254

191.3.1 configurations have been changed. The current change number is 6, the ch
ange loop count is 0, and the maximum number of records is 4095.

S4:

[S4]interface Vlanif 
May 27 2022 18:43:42-08:00 S4 DS/4/DATASYNC_CFGCHANGE:OID 1.3.6.1.4.1.2011.5.25.
191.3.1 configurations have been changed. The current change number is 4, the ch

191.3.1 configurations have been changed. The current change number is 5, the ch
ange loop count is 0, and the maximum number of records is 4095.	
[S4]ip route-static 0.0.0.0 0 10.0.5.254
[S4]

九、验证配置

检测R1与S3的连通性,即VLAN2与VLAN3的连通性:

R1:

eNSP三层交换实现vlan中的通信 ensp三层交换机实现vlan间路由_eNSP三层交换实现vlan中的通信_03

检测R1与R2之间,即VLAN3与VLAN4的连通性:

R1:

eNSP三层交换实现vlan中的通信 ensp三层交换机实现vlan间路由_网络协议_04

上述信息表表明VLAN3与VLAN4之间不能通信,使用Trancert命令查看测试原因:

R1:

eNSP三层交换实现vlan中的通信 ensp三层交换机实现vlan间路由_网络_05

上述信息表明数据包只能到达VLAN3的网关设备,然后在S1上查看是否具有到达目的VLAN网段的路由条目:

S1:

eNSP三层交换实现vlan中的通信 ensp三层交换机实现vlan间路由_eNSP三层交换实现vlan中的通信_06

从路由表可以看出,这里是没有到目的网段10.0.4.0的路由条目的,所以数据包就不能转发到目的网段.

十、配置OSPF

由于S1上缺少路由条目,这里就可以使用OSPF动态获取.

在S1和S2上配置OSPF:

S1:

hange loop count is 0, and the maximum number of records is 4095.
[S2-ospf-1-area-0.0.0.0]q
[S2-ospf-1]q
[S2]

待收敛完成后,查看S1路由表:

S1:

eNSP三层交换实现vlan中的通信 ensp三层交换机实现vlan间路由_IP_07

此时路由表已经有了我们需要的路由条目,然后再来测试VLAN3到VLAN4的连通性:

R1:

eNSP三层交换实现vlan中的通信 ensp三层交换机实现vlan间路由_链路_08

可以看到,此时R1与R2已经可以进行通信了.
