Hi

Here a sample how you can configure the subinterfaces:

int fastEthernet 0/0.1

encapsulation dot1Q 1

ip address 10.0.0.1 255.255.255.0

!

int fastEthernet 0/0.2

encapsulation dot1Q 2

ip address 192.168.1.1 255.255.255.0

!

int fastEthernet 0/0.3

encapsulation dot1Q 3

ip address 172.16.1.1 255.255.255.0

Here also a link to how to configure interVLAN routing using a 2621:

Thank you for reply!

I saw the sample ,but the way can not configure the router 2621 with cisco ios 12(8),how to do ?

Your IOS looks like is a IP only version. Upgrade to IP plus to configure encapsulation command under subinterface. ISL and dot1q trunking are supported only if you have a min of IP plus.
