Arun,
I'm not completely sure, but I think that you have to run 12.0 or higher to
do trunking on a router. You might want to double check that though.In the
mean time, here are examples of a working trunking config on a 2924XL that I
work with and the complementing router config.
................Switch...............
switchport access vlan 1
switchport trunk encapsulation dot1q (you would use isl instead)
switchport mode trunk
................Router...............
interface FastEthernet0/0
no ip address
no ip directed-broadcast
speed 100
full-duplex
!
interface FastEthernet0/0.1
description Management
encapsulation dot1q 1
ip address 10.1.0.1 255.255.255.0
no ip directed-broadcast
Hope this helps,
Karen
