4400 does not see router when converting MPLS
We currently have a 3Com SuperStack3 4400 switch hooked up to a Cisco 1700 router running off Frame and all is fine. Once we try to get this up on a new MPLS circuit, the switch disapears.
We have a 2800 Cisco router at our HQ in Seville, Ohio. We also have a Cisco 3560 Switch at our Seville HQ's. The Qwest MPLS circuit goes from Seville to our Chicago site. At the Chicago site we have that 3Com 4400 switch. Once we convert to MPLS, our switch does not see the Qwest owned Adtran router (We are removing our 1700 router from the equation and using a Qwest owned Adtran router).
The 3 Com switch IP is 192.168.5.35
3com switch info below:
Interface Description | Physical Address | Network Address | Mapping Type |
Management Port 192.168.5.35 on unit 1 | 0050-547D-41BE | 192.168.5.1 | dynamic |

__________________________________________________________________________________________
On our side in Seville, Ohio we have created a subnet on the Cisco router and 2 VLANS on the 3560 switch. The whole idea of this is to run the new MPLS circuit off our switch in Seville Ohio to Chicago. At Chicago, there is a Qwest managed adtran router which is onsite in Chicago, and that is connected to our 3Com 4400 switch. We have tried to convert this 3 times, and each time the 3Com switch dispears. We can see the 3com IP on our arp table, but no MAC or anything else.
Below is the Cisco configs we have going. The Qwest Adtran router IP is 192.168.5.1 and the DG of the Qwest Adtran router is 192.168.10.2 (MPLS going back to us in Seville via 192.168.10.1)

Can anyone figure out why we don't see our 3Com after going to the Qwest MPLS circuit?
