Inter VLAN routing by a layer 3 swith
-
Inter VLAN routing by multilayer switch is recommended
example:
-
multilayer switch configuration:
switch(config)#vlan 2
switch(config-vlan)#exit
switch(config)#vlan 3
switch(config-vlan)#exit
switch(config)#interface fastethernet 0/1
switch(config-if)#switchport mode trunk
switch(config-if)#switchport trunk allowed vlan 2,3
switch(config-if)#exit
switch(config)#interface vlan 2
switch(config-if)#no shutdown
switch(config-if)#ip address 192.168.1.1 255.255.255.0
switch(config-if)#exit
switch(config)#interface vlan 3
switch(config-if)#no shudown
switch(config-if)#ip address 192.168.2.1 255.255.255.0
switch(config-if)#exit
switch(config)# ip routing
switch(config)#^z
switch#wr
-
Now layer 2 switch configuration:
switch(config)#interface fastethernet 0/1
switch(config-if)#switchport mode trunk
switch(config-if)#switchport trunk allowed vlan 2,3
switch(config-if)#exit
switch(config)#inerface fastethernet 0/6
switch(config-if)#switchport mode access
switch(config-if)#switchport access vlan 2
switch(config-if)#exit
switch(config)#interface fastethernet 0/5
switch(config-if)#switchport mode access
switch(config-if)#switchport access vlan 3
switch(config-if)#exit
switch(config)#^z
switch#wr
