    - TE Topologies are protocol independent. Information about
      topological elements may be learnt via link-state protocols, but
      the topology can exist without being dependent on any particular
      protocol.
 
    - TE Topology may not be congruent to the routing topology in a
      given TE System. The routing topology is constructed based on
      routing adjacencies. There isn't always a one-to-one association
      between a TE-link and a routing adjacency. For example, the

    - Each TE Topological element has at least one information source
      associated with it. In some scenarios, there could be more than
      one information source associated with any given topological
      element.
 
    - TE Topologies can be hierarchical. Each node and link of a given
      TE Topology can be associated with respective underlay topology.
      This means that each node and link of a given TE Topology can be
      associated with an independent stack of supporting TE Topologies.
