Re: about vlan routing

You can try the following:

!

interface FastEthernet0/1

switchport access vlan 10

switchport mode access

no ip address

!

interface FastEthernet0/2

switchport access vlan 10

switchport mode access

no ip address

!

interface FastEthernet0/3

switchport access vlan 20

switchport mode access

no ip address

!

interface FastEthernet0/4

switchport access vlan 20

switchport mode access

no ip address

!

!

interface Vlan10

ip address 10.12.82.254 255.255.255.192

no shutdown

!

interface Vlan20

ip address 172.16.1.254 255.255.255.0

no shutdown

!

Typically, the interface vlan's ip address is the default gateway of the hosts.
