大家好,又见面了,我是你们的朋友全栈君。
傍晚时分,你坐在屋檐下,看着天慢慢地黑下去,心里寂寞而凄凉,感到自己的生命被剥夺了。当时我是个年轻人,但我害怕这样生活下去,衰老下去。在我看来,这是比死亡更可怕的事。——–王小波

案例(更合理的使用三层交换机)
:交换机、三层交换、路由构建网络
需求:实验室有一条接入网线,该网线直接连接PC,PC的IP设置为 192.168.4.xxx 后可以访问服务器机房的服务器(IP为192.168.5.1),但是想要实验室内的多台PC都能访问 192.168.5.1,请问交换机应该如何配置?
综合组网 |
---|
第一步:设计好网络拓扑结构;为了缓解三层交换机的压力,通常连接外部网路需要连接一个路由器。路由器的功能要比三成交换机强大。 |
第二步
:在PC1、PC2 和 PC3 及PC4 中配置IP地址,子网掩码和网关;PC1: IP地址:192.168.1.1/24 网关:192.168.1.254
PC2: IP地址:192.168.2.1/24 网关:192.168.2.254
PC3: IP地址:192.168.3.1/24 网关:192.168.3.254
PC4: IP地址:192.168.5.1/24 网关:192.168.5.254
第三步
:在二层交换机 (S3700) LSW1上创建VLAN;<LSW1>system-view
[LSW1]vlan batch 2 to 3 #二层交换机上创建vlan
第四步
:将接口加入到交换机 (S3700) LSW1相应的vlan中;[LSW1]interface Ethernet 0/0/2
[LSW1-Ethernet0/0/2]port link-type access
[LSW1-Ethernet0/0/2]port default vlan 2
[LSW1-Ethernet0/0/2]display vlan #查看结果
[LSW1]interface Ethernet 0/0/3
[LSW1-Ethernet0/0/3]port link-type access
[LSW1-Ethernet0/0/3]port default vlan 3
[LSW1-Ethernet0/0/3]display vlan #查看结果
第五步
:在二层交换机LSW1 (S3700) 和三层交换机LSW2(S5700) 上配置trunk(中继链路)#在二层交换机LSW1 (S3700)的Ethernet 0/0/4接口配置trunk
[LSW1]interface Ethernet 0/0/4
[LSW1-Ethernet0/0/4]port link-type trunk
[LSW1-Ethernet0/0/4]port trunk allow-pass vlan all
[LSW1-Ethernet0/0/4]quit
[LSW1]display current-configuration
#在三层交换机LSW2(S5700)的Ethernet 0/0/4接口配置trunk
[LSW2]interface GigabitEthernet 0/0/1
[LSW2-GigabitEthernet0/0/1]port link-type trunk
[LSW2-GigabitEthernet0/0/1]port trunk allow-pass vlan all
[LSW2-GigabitEthernet0/0/1]quit
[LSW2]display current-configuration
第六步
:在三层交换机LSW2(S5700)上创建vlan,并将接口GE 0/0/2加入到vlan 4中<LSW2>system-view
[LSW2]vlan batch 2 to 4 #三层交换机上创建vlan
[LSW2]interface GigabitEthernet 0/0/2
[LSW2-GigabitEthernet0/0/2]port link-type access
[LSW2-GigabitEthernet0/0/2]port default vlan 4
[LSW2-GigabitEthernet0/0/2]display vlan #查看结果
第七步
:在三层交换机 LSW2(S5700) 的虚接口上配置IP#在vlan 1上配置IP地址
[LSW2]interface Vlanif 1
[LSW2-Vlanif1]ip address 192.168.1.254 24
[LSW2-Vlanif1]quit
#在vlan 2上配置IP地址
[LSW2]interface Vlanif 2
[LSW2-Vlanif2]ip address 192.168.2.254 24
[LSW2-Vlanif2]quit
#在vlan 3上配置IP地址
[LSW2]interface Vlanif 3
[LSW2-Vlanif3]ip address 192.168.3.254 24
[LSW2-Vlanif3]quit
#在vlan 4上配置IP地址
[LSW2]interface Vlanif 4
[LSW2-Vlanif4]ip address 192.168.4.1 24
[LSW2-Vlanif4]quit
[LSW2]display ip routing-table | include /24 #查看虚接口配置信息
第八步
:在路由器AR1(AR2220) 上给接口配置IP地址<AR1>system-view
[AR1]interface GigabitEthernet 0/0/0
[AR1-GigabitEthernet0/0/0]ip address 192.168.4.2 24
[AR1]interface GigabitEthernet 0/0/1
[AR1-GigabitEthernet0/0/1]ip address 192.168.5.254 24 #在路由器上给5.0网段配置网关
[AR1]display ip routing-table | include /24 #查看接口IP地址配置信息
第九步
:在三层交换机LSW2(S5700)上配置静态路由<LSW2>system-view
[LSW2]ip route-static 192.168.5.0 24 192.168.4.2 #目标网段,子网掩码,下一跳地址
[LSW2]display ip routing-table | include /24
第十步
:在路由器AR1(AR2220) 上配置静态路由<AR1>system-view
[AR1]ip route-static 192.168.1.0 24 192.168.4.1 #目标网段,子网掩码,下一跳地址
[AR1]ip route-static 192.168.2.0 24 192.168.4.1
[AR1]ip route-static 192.168.3.0 24 192.168.4.1
[AR1]display ip routing-table | include /24
