I am studying for my CCNA, playing around with a few of the dirfferent concepts with my hardware. I am trying to setup a router on a stick configuration using a 2600 router and a 2900 catalyst switch.
I have the FastEthernet 0/1 port plugged into Fa0/1 on the switch. The switch has three vlans setup with a client on each vlan
I have set the port on the switch as follows:
Switch(config-if)#switchport mode Trunk
Switch(config-if)#switchport trunk native vlan 1
Switch(config-if)#switchport trunk encapsulation isl
When I try to set the router, I get this:
rt01(config)#int fa0/1
rt01(config-if)#no ip add
rt01(config-if)#exit
rt01(config)#int fa0/1.1
rt01(config-subif)#encapsulation isl
^
% Invalid input detected at '^' marker.
I cannot set the encapsulation on the sub interface, ISL or dot1q - it doesn't recognize the "encapsulation command" command at all.
My show version is below. I can't confirm one way or another if this image supports IP Plus (which I've been told may be the problem), but based on the message I get when trying to set the IP address on the subif I would think it does..?
My router sh ver shows:

Hi
c2600-i-mz.123-6.bin is the IP (not IP Plus) version of software. This doesn't support dot1q or ISL trunks.
The IP Plus would be required for this feature (image name for the plus equivalent of your image would be c2600-is-mz.12.3-6.bin)

Thank you for the reply. At least I know what the "problem" is now.
Is there anyway I can get the IP Plus IOS from Cisco or elsewhere? As far as I can tell, I can't register to download it from Cisco as an individual. I purchased the router from a hardware salvage place so i don't have any kind of licensing or purchase info to use...
