For L3VPN discovery, the MPLS Topology Server component of MPLS Manager is able to discover and model MPLS Layer 3 VPN entities. It relates the discovered L3VPNs to the MPLS and transport domains by creating logical and physical relationships between the L3VPN entities and the underlying MPLS entities and Layer 3 devices.

The MPLS Topology Server requires a Level 3 VPN feature license for the discovery of L3VPNs. The VMware Smart Assurance System Administration Guide provides information about licensing.
