Iam enabling MPLS (LDP) on the backbone of my network. The connected routers are 7613 at the central location and 7200 at remote location. Both sides the e1 termination are on Channelised E1 ports

The topology is attached

The moment I enable ldp neighborship bet the routers i loose connectivity to the remote location routers ethernet and loopback ips. But all the device in the remote location lan say other routers switches and pcs are reachable

I suspect some mtu issues

Commands used globally are

mpls ip

mpls label protocol ldp

Interface level (serial interface)

mpls ip

mpls label protocol ldp

Some help is appreciated

Mobile operators can also lower operating and capital expenditures (OpEx and CapEx) through the consolidation and migration of their existing ATM, TDM, and Frame Relay networks to a converged IP/MPLS backbone and VPN technologies at Layer 2 and Layer 3. Cisco IP/MPLS can operate over MPLS-enabled ATM switches, which helps protect investments as mobile operators transition from ATM to IP and transform their businesses
