Import of topology

By default, as indicated in Figure 19, the MPLS Topology Server imports only the objects that it is designed to manage. To accomplish that end, IP Availability Manager, when it is configured to perform MPLS light discovery, not only performs its traditional discovery of network objects, but also creates MPLS topology collection sets from the discovered network objects. One such set is named MPLS-System.

MPLS-System contains MPLS-enabled router and switch devices as well as the non-MPLS-enabled devices that connect directly to the MPLS-enabled devices. An MPLS-enabled device is a PE, P, or Multi-VRF CE, and a non-MPLS-enabled device is a CE (non-Multi-VRF CE) or other provider device that has no MPLS functionality.

Implied in Figure 19 is that a user can use the Disable_Light_Discovery parameter to change the default behavior, to configure the MPLS Topology Server to import all router and switch devices from IP Availability Manager.
