CatOS router on a stick configuration

Hi I'm having an issue setting up a router on a stick configuration with a 4006 running CatOS and a 2621 router. I have set up vlans on the 4006, and set up sub interfaces on the 2621 that corrospond to the different vlan's however when I connect a workstation to the vlan I can only ping out to the ip address of the subinterface on the router not the other VLAN's or to the internal interface on the PIX or internet. I've had this config working on a 2621 previously when working with an IOS switch so I'm wondering if the issue is just my lack of knowledge of CatOS. I have posted the configs of the different devices below as well as the topology, any help with this would be appreciated.

Why are you hard coding the speed/duplex? Unless you specific set the duplex on your workstations (which can be difficult to find), you'll have a duplex conflict on every one. I'd recommend auto speed, auto duplex on everything.

Most likely this is the problematic line. I'd recommend getting 'desireable' out, as that signals the switch to try to negotiate dynamic trunking protocol with the switch on the other side. You don't have a switch on the other side, and a router isn't going to talk dynamic trunking protocol.

Is this port in trunking mode now? What does the port status show? show trunk 3/48

I can take out the hard coded speed, I had read that it was best to hard code the speed and duplex on both ends of the trunk at least

The status does show trunking.

What should I use for this line?

set trunk 3/48 desirable dot1q 1-1005,1025-4094

I also tried below with the same results.

set trunk 3/48 on dot1q 1-1005,1025-4094

A long long time ago. Auto is definately desireable, especially since GigE requires it.

Hmm, should be working then.

That is the proper form.

Make sure the VLANs exist the same on both sides (show vlan). Use VTP transparent mode (I'd avoid VTP altogether, transparent mode makes it invisible).

Here are config snippets out of a working config exactly as you are trying to do, albeit slightly different gear.

set vtp mode transparent vlan set vlan 103 2/20-29 set vlan 104 2/30-39 set trunk 2/48 on dot1q 1-1005,1025-4094 set trunk 2/49 on dot1q 1-1005,1025-4094
