OSPF TE Extension - No Topology (OSPFv2 only)

When OSPF traffic engineering is enabled on the routing device, the traffic engineering parameters are populated in the traffic engineering database. The traffic engineering database is used exclusively for calculating explicit paths for the placement of LSPs across the physical topology. The Constrained Shortest Path First (CSPF) algorithm uses the traffic engineering database to compute the paths that MPLS LSPs take. RSVP uses this path information to set up LSPs and to reserve bandwidth for them. This feature disables the dissemination of link-state topology information.
