三层交换配置路由
目的:
1.实现多交换机不同Vlan间通信.
2.基于三层交换机配置路由,实现全网互通.
拓扑图:
步骤:
1. 配置PC主机的IP,掩码,网关.
2. 在二层交换机LSW1和LSW2上配置VLAN
[Huawei]sysname sw1 //配置LSW1
[sw1]vlan 2
[sw1-vlan2]quit
[sw1]vlan 3
[sw1-vlan3]quit
[sw1]interface e0/0/1
[sw1-Ethernet0/0/1]port link-type access
[sw1-Ethernet0/0/1]port default vlan 1
[sw1-Ethernet0/0/1]quit
[sw1]interface e0/0/2
[sw1-Ethernet0/0/2]port link-type access
[sw1-Ethernet0/0/2]port default vlan 2
[sw1-Ethernet0/0/2]quit
[sw1]interface e0/0/3
[sw1-Ethernet0/0/3]port link-type access
[sw1-Ethernet0/0/3]port default vlan 3
[sw1-Ethernet0/0/3]quit
[sw1]interface g0/0/1
[sw1-GigabitEthernet0/0/1]port link-type trunk
[sw1-GigabitEthernet0/0/1]port trunk allow-pass vlan all
[sw1-GigabitEthernet0/0/1]quit
[Huawei]sysname sw2 //配置LSW2
[sw2]vlan 4
[sw2-vlan4]quit
[sw2]vlan 5
[sw2-vlan5]quit
[sw2]interface e0/0/1
[sw2-Ethernet0/0/1]port link-type access
[sw2-Ethernet0/0/1]port default vlan 4
[sw2-Ethernet0/0/1]quit
[sw2]interface e0/0/2
[sw2-Ethernet0/0/2]port link-type access
[sw2-Ethernet0/0/2]port default vlan 5
[sw2-Ethernet0/0/2]quit
[sw2]interface g0/0/2
[sw2-GigabitEthernet0/0/2]port link-type trunk
[sw2-GigabitEthernet0/0/2]port trunk allow-pass vlan all
[sw2-GigabitEthernet0/0/2]quit
3. 配置三层交换机

[sw3-GigabitEthernet0/0/3]quit
[sw3]interface vlanif 6
[sw3-Vlanif6]ip address 192.168.6.254 24
[sw3-Vlanif6]quit
[sw3]ip route-static 192.168.7.0 255.255.255.0 192.168.6.1
