MPLS-Signaled LSP Configuration Guidelines

MPLS-signaled label-switched paths (LSPs) run from a specific ingress router to a specific egress router. This chapter describes how to configure LSPs. You can configure an LSP so that the JUNOS Software makes all forwarding decisions, or you can configure some or all routers in the path.

For instructions for configuring the ingress router and other routers on the path, see MPLS Router Configuration Guidelines.
