During this phase (Phase 3) of the L3VPN discovery process, which starts after per-device discovery completes, the MPLS Topology Server creates instances of the following classes by combining the information that is collected during per-device L3VPN and MPLS discovery:

  • VPN

  • MulticastVPN

  • MulticastGroup

    Also, during this phase, the MPLS Topology Server creates the relationships that associate the L3VPN with the underlying LSPs.
