Overview

A static Constraint-based Routed Label Switched Path (CRLSP) is established by manually specifying the incoming label, outgoing label, and required bandwidth on each node (ingress, transit, or egress node) of the forwarding path. If the device does not have enough bandwidth resources required by a CRLSP, the CRLSP cannot be established.

Static CRLSPs consume fewer resources, but they cannot automatically adapt to network topology changes. Therefore, static CRLSPs are suitable for small and stable networks with simple topologies.

Follow these guidelines to establish a static CRLSP:
