about vlan routing

[yongjunh]

I have a catalyst 3550-48(emi) 3 layer switch, in my lan there were some vlan and another ip address ,how can i config the 3550-48 to make the clients in the different vlans can communicate with each other.

ex

vlan 10.12.82.0/192 and 172.16.1.0/24

thanks

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.
