I have 1924 switch with enterprise version.
I have 10 vlans and want to setup intervlan using 2620/2621.
I define encapsulation isl on router and enable trunking on switch port.
I have connected pc on different subnets on different vlan ports
still they can not ping.
I enable the routing already in router for these subnets.
Could anyone find any missing part here or there is any fix for it and whether
it is possible or not.
Thanks

From the description you seem to have got the overall idea..and configured it. correctly. but it is not working ;)
Some of things may be redundant but I would ask anyway
1) Did you configure correct subnet ip address on the router on each of the sub-interfaces ?
2) Did you define the correct default gateway from the PC ?
3) Can the PC ping the default gateway ?
You may want to provide some outputs for us to troubleshoot further.
You can use this URL for router config only (this example is not connecting to a 1900 switch but the router config is same anyway)

Hope this helps

Hi
on you interface vlan# have you enabled ISL? this is a common mistake with intervan routing.
Example-------
int vlan 20 isl
ip address
make sure your ip address is the same for the corrosponding vlan
hope it works
cheers
