[CCNA experiment sharing] routing between VLANs of layer 3 switches

2022-07-24 21:33:00 【GLAB-Mary】

The experiment purpose ：

Use L3 Switch to do Vlan Routing between nodes

Experimental instructions ：

Although single arm routing can achieve different vlan To communicate with each other , Because of poor performance , So... Is not recommended . Generally, high-performance routes are used between different network segments in medium and large-scale networks L3 Switch .

Experimental Topology ：

Insert picture description here

The experimental steps ：

1. To configure Core Switch

Switch(config)#hostname Core

Core(config)#vlan 10

Core(config-vlan)#name engineering

Core(config-vlan)#vlan 20

Core(config-vlan)#name RD

Core(config-vlan)#vlan 30

Core(config-vlan)#name ServerFarm

Core(config-vlan)#vlan 40

Core(config-vlan)#name MGT-vlan

Core(config-vlan)#exit

Core(config)#int vlan 10

Core(config-if)#no shut

Core(config-if)#ip address 192.168.10.254 255.255.255.0{ Create three layers SVI Interface , And configuration IP Address }

Core(config-if)#int vlan 20

Core(config-if)#ip address 192.168.20.254 255.255.255.0

Core(config-if)#no shutdown

Core(config-if)#int vlan 30

Core(config-if)#ip address 192.168.30.254 255.255.255.0

Core(config-if)#no shutdown

Core(config-if)#int vlan 40

Core(config-if)#ip address 192.168.40.254 255.255.255.0

Core(config-if)#no shutdown

Core(config-if)#exit

Core(config)#ip routing{ Enable L3 The routing function of the switch }

Core(config)#int range f0/1 - 2

Core(config-if-range)#switch mode access

Core(config-if-range)#switch access vlan 30

Core(config-if-range)#spanning-tree portfast

Core(config-if-range)#exit

Core(config)#int f0/24

Core(config-if)#switchport trunk encapsulation dot1q

Core(config-if)#switchport mode trunk

Core(config-if)#exit

Core(config)#line vty 0 4

Core(config-line)#login

Core(config-line)#password G-LAB

Core(config-line)#exit

Core(config)#enable secret G-LAB

2. To configure ED-SW Switch

Switch>enable

Switch#

Switch(config)#hostname ED-SW

ED-SW(config)#vlan 10

ED-SW(config-vlan)#name engineering

ED-SW(config-vlan)#vlan 20

ED-SW(config-vlan)#name RD

ED-SW(config-vlan)#vlan 40

ED-SW(config-vlan)#name MGT-vlan

ED-SW(config-vlan)#exit

ED-SW(config)#int range f0/1 – 5

ED-SW(config-if-range)#switch mode access

ED-SW(config-if-range)#switch access vlan 10

ED-SW(config-if-range)#spanning-tree portfast

ED-SW(config)#int range f0/6 – 10

ED-SW(config-if-range)#switch mode access

ED-SW(config-if-range)#switch access vlan 20

ED-SW(config-if-range)#spanning-tree portfast

ED-SW(config-if-range)exit

ED-SW(config)#interface fa0/12

ED-SW(config-if)#switch mode trunk

ED-SW(config-if)#exit

ED-SW(config)#int vlan 40

ED-SW(config-if)#ip address 192.168.40.200 255.255.255.0

ED-SW(config-if)#no shut

ED-SW(config-if)#exit

ED-SW(config)#ip default-gateway 192.168.40.254

ED-SW(config)#line vty 0 4

ED-SW(config-line)#login

ED-SW(config-line)#password G-LAB

ED-SW(config-line)#exit

ED-SW(config)#enable secret G-LAB
