mpls te cspf path-selection adjacency-sid

Function

The mpls te cspf path-selection adjacency-sid command enables a device to run CSPF to compute an LSP in an SR-MPLS TE strictly based on adjacency SIDs.

The undo mpls te cspf path-selection adjacency-sid command disables a device from running CSPF to compute an LSP in an SR-MPLS TE strictly based on adjacency SIDs.

By default, this function is disabled.

Usage Guidelines

Usage Scenario

If the SR-MPLS TE ingress computes path, to enable the ingress to run CSPF to compute an LSP in an SR-MPLS TE strictly based on adjacency SIDs, run the mpls te cspf path-selection adjacency-sid command.

Prerequisites

The following operations have been performed:

An MPLS TE tunnel has been established using the interface tunnel command.
MPLS TE has been configured as a tunneling protocol using the tunnel-protocol command.
SR-MPLS TE has been configured using the mpls te signal-protocol segment-routing command to establish TE tunnels.

# Enable a device to run CSPF to compute an LSP in an SR-MPLS TE strictly based on adjacency SIDs.
