Hierarchy of RSVP LSPs Terminology
F
Forwarding adjacency
A traffic engineering link created by a forwarding adjacency LSP. You can create a forwarding adjacency between two routers in a network by configuring a forwarding adjacency LSP. Forwarding adjacencies can only be statically configured. However, you can configure OSPF to advertise the forwarding adjacency to other routers. When an RSVP LSP traverses a forwarding adjacency, existing MPLS features such as fast reroute continue to function.
Forwarding adjacency LSP
An RSVP LSP used to tunnel other RSVP LSPs; forms the basis for a forwarding adjacency.
