To configure MPLS signaled LSPs, you create an LSP that runs from the ingress router to the egress router. (For information on LDP signaled LSPs, see Configure LDP.) To create the LSP, you configure only the ingress router; you do not have to configure any other routers. You can configure the LSP so that the JUNOS software makes all the forwarding decisions, or you can configure some or all of the routers in the path. The LSP is set up by RSVP, through RSVP signaling messages. The JUNOS software automatically negotiates, assigns, releases, and reuses labels. Automatically assigned labels have a value from 1024 through 1048575.
To configure signaled LSPs across a network, perform the following tasks:
For a configuration example, see Examples: Configure Signaled LSPs.
