Software Configuration of ATM ISE Line Cards for Cisco 12000 Series Routers
•
Prerequisites
Before configuring AToM, ensure that the network is configured as follows:
•
•
•
Configuring ATM AAL5 over MPLS
ATM AAL5 over MPLS encapsulates ATM AAL5 SDUs in MPLS packets and forwards them across the
MPLS network. Each ATM AAL5 SDU is transported as a single packet. Perform this task to enable
ATM AAL5 over MPLS.

OAM Emulation: Allows for sending a remote defect indication (RDI) in response to an alarm
indication signal (AIS) without passing it along the MPLS network to the egress provider edge (PE).
It also allows for sending F5 loopback cells of loopback point (with loopback indication equal to 0)
in response to F5 loopback cells of source point (with loopback indication equal to 1) without
passing them along the MPLS network to the egress PE. In addition, it drops F5 continuity check
cells without passing them along the MPLS network to the egress PE.

Configure IP routing in the core so that the PE routers can reach each other via IP.
Configure MPLS in the core so that a label switched path (LSP) exists between the PE routers.
Configure a loopback interface for originating and terminating Layer 2 traffic. Make sure the PE
routers can access the other router's loopback interface.
