SVI (Switch Virtual Interfaces) We use the SVI for inter vlan routing. In this scenario I will configure the access list with SVI. In this scenario I want to permit vlan 10 network to vlan 50 Server farm. Vlan 10 and vlan 20 can communicate each other. First create vlan and then interface vlan#. Switch(config)#vlan 10 Switch(config)#interface vlan 10 Switch(config-if)#ip address 192.168.10.254 255.255.255.0 Switch(config)#vlan 20 Switch(config)#interface vlan 20 Switch(config-if)#ip address 192.168.20.254 255.255.255.0 Switch(config)#vlan 50 Switch(config)#interface vlan 50 Switch(config-if)#ip address 192.168.50.254 255.255.255.0 when we finish the vlan interface create make sure the switch port are belong to each vlan. Port to vlan assign configure is Switch(config)#interface g0/1 Switch(config-if)#switchport access vlan 10 Switch(config)#interface g0/2 Switch(config-if)#switchport access vlan 20 Switch(config)#int
