Hierarchy of RSVP LSPs
Forwarding adjacencies are configured and managed as point-to-point traffic engineering links by including statements at the [edit protocols link-management] hierarchy level. For the forwarding adjacency to function properly, you also need to make RSVP aware of the forwarding adjacency by configuring the corresponding peer interface at the [edit protocols rsvp] hierarchy level.
Although forwarding adjacency LSPs are configured and managed as traffic engineering links on the local router, it is not necessary to advertise these traffic engineering links to other routers in the network. However, if you want to automatically forward MPLS traffic over the forwarding adjacency or want other routers to compute paths over the forwarding adjacency, you must configure OSPF to advertise the forwarding adjacency to the other routers in the network and add the forwarding adjacency to the traffic engineering database. OSPF is the only supported interior gateway protocol (IGP).
