Full discovery

During the initial full discovery, the MPLS Topology Server component of MPLS Manager populates its repository with router and switch topology from IP Availability Manager, and then probes the devices to discover MPLS, VPN, and (optional) BGP topology. The initial full discovery occurs when an IP Availability Manager is added as a source to the MPLS Topology Server, as explained in “Initiating discovery” on page 125.

Thereafter, whenever an IP Availability Manager source completes a discovery (an initial discovery, a full discovery, a pending discovery, or a single-device discovery), the MPLS Topology Server performs a discovery as described in “Topology synchronization” on page 126.
