Hello everyone, in this tutorial I’ll discuss about how to configuration intervlan routing on Switch layer 3. Before I have discuss about intervlan routing on router device https://www.taufiknurhuda.web.id/2022/07/03/configuration-intervlan-routing-router-on-stick-on-cisco-packet-tracer/. There is a slight difference for the configuration between router and switch L3.
The following is the topologi are used :
And the following is step by step configuration :
Configure SW1 :
Switch>en Switch#config t Switch(config)#hostname SW1
Add Vlan interface :
SW1(config)#vlan 10 SW1(config-vlan)#exit SW1(config)#vlan 20 SW1(config-vlan)#exit
Assign interface ethernet to each vlan :
SW1(config)#int e0/1 SW1(config-if)#sw mode acc SW1(config-if)#sw acc vlan 10 SW1(config-if)#exit SW1(config)#int e0/2 SW1(config-if)#sw mode acc SW1(config-if)#sw acc vlan 20 SW1(config-if)#exit
Configure trunk port
SW1(config)#int e0/0 SW1(config-if)#sw trunk encapsulation dot1q SW1(config-if)#sw mode trunk SW1(config-if)#exit
Configure SW 2 :
Switch>en
Switch#config t
Switch(config)#hostname SW2
Add Vlan interface :
SW2(config)#vlan 10 SW2(config-vlan)#exit SW2(config)#vlan 20 SW2(config-vlan)#exit
Assign interface ethernet to each vlan :
SW2(config)#int e0/1 SW2(config-if)#sw mode acc SW2(config-if)#sw acc vlan 10 SW2(config-if)#exit SW2(config)#int e0/2 SW2(config-if)#sw mode acc SW2(config-if)#sw acc vlan 20 SW2(config-if)#exit
Configure trunk port
SW2(config)#int e0/0 SW2(config-if)#sw trunk encapsulation dot1q SW2(config-if)#sw mode trunk SW2(config-if)#exit SW2(config)#
Check VLAN status on SW1
SW1#show vlan brief VLAN Name Status Ports ---- -------------------------------- --------- ------------------------------- 1 default active Et0/3 10 VLAN0010 active Et0/1 20 VLAN0020 active Et0/2 1002 fddi-default act/unsup 1003 token-ring-default act/unsup 1004 fddinet-default act/unsup 1005 trnet-default act/unsup SW1#
Check VLAN status on SW2
SW2#show vlan brief VLAN Name Status Ports ---- -------------------------------- --------- ------------------------------- 1 default active Et0/3 10 VLAN0010 active Et0/1 20 VLAN0020 active Et0/2 1002 fddi-default act/unsup 1003 token-ring-default act/unsup 1004 fddinet-default act/unsup 1005 trnet-default act/unsup SW2#
Configure SW L3
SWL3(config)#vlan 10 SWL3(config-vlan)#exit SWL3(config)#vlan 20 SWL3(config-vlan)#exit SWL3(config)#int vlan 10 SWL3(config-if)#ip add 192.168.10.1 255.255.255.0 SWL3(config-if)#no shutdown SWL3(config-if)#exit SWL3(config)#int vlan 20 SWL3(config-if)#ip add 192.168.20.1 255.255.255.0 SWL3(config-if)#no shutdown SWL3(config-if)#exit SWL3(config)# SWL3(config)#int range e0/1-2 SWL3(config-if-range)#sw trunk encapsulation dot1q SWL3(config-if-range)#sw mode trunk SWL3(config-if-range)#exit
Show vlan :
SWL3#show vlan brief VLAN Name Status Ports ---- -------------------------------- --------- ------------------------------- 1 default active Et0/0, Et0/3 10 VLAN0010 active 20 VLAN0020 active 1002 fddi-default act/unsup 1003 token-ring-default act/unsup 1004 fddinet-default act/unsup 1005 trnet-default act/unsup

Configure IP Routing on Switch L3 to activate L3 mode :
SWL3(config)#ip routing SWL3(config)#
