I'm trying to use the switch 3750 to route between a couple of networks. The switch is connected to the router but I do not want the router to route these two networks.
The default network is 10.20.57.128/25, the second network is 10.57.9.0/28
Here's my config...

I hope your running EMI software.
you don't need to assign the port connecting to the router an IP address. It can happily live in VLAN 1.
By the looks of your config, you only have 4 ports not in VLAN 1 and they are all configured in a port-channel.
Is you switch configured as a default gateway or are hosts still sending data to the router which is connected to a shut down port?
Can you draw up a picture so I can understand where the router connects back into the 140 VLAN..

Hi Steve,
Thanks for responding.
I am running EMI software on the 3750 and I have a supIV with enhanced software for the Cat4006.
wkstn A 10.20.57.141 ---> cat 3750 ----> 3640 router (10.57.2.129) ---WAN
| |
| |
wkstn B 10.57.2.158----->catalyst 4006 --------------->3640 router (10.57.2.138)
Currently the gateway for wkstn A is 10.57.2.129, gateway for wkstn B 10.57.2.158.
What I am trying to do is when wkstn A needs to talk to wkstn B, I need it to use the cat 3750 to the cat 4006 to wkstn B instead of using the 3640 routers.
What am proposing to do is create two vlans 10.20.57.128/25 and 10.57.9.0/28 on cat3750 and vlans 10.57.2.128/25 and 10.57.9.0/28 on cat4006. When wkstnA wants to talk to wkstnb, it would use the 10.57.9.0 vlan.
The other bug to this is if wkstn A wants to talk to anything in the WAN, it has to use the 3640 routers.
Does this make any sense? I've been trying to explain this to TAC but they don't seem to get it. They're saying I can't do this.
Thanks..JOy
