mpls te binding-sid

Function

The mpls te binding-sid command sets a binding SID for an SR-MPLS TE tunnel.

The undo mpls te binding-sid command deletes a binding SID for an SR-MPLS TE tunnel.

By default, no binding SID is set for an SR-MPLS TE tunnel.

Usage Guidelines

Usage Scenario

When configuring an intra-AS SR-MPLS TE tunnel, set a binding SID for the tunnel. The binding SID identifies an SR-MPLS TE tunnel and replaces the label stack of an SR-MPLS TE tunnel.

Using binding BIDs reduces the number of labels in a label stack on an NE, which helps build a large-scale network. The controller uses both binding SIDs and BGP peer SIDs to compute a path over which an inter-AS E2E SR-MPLS TE tunnel is established.

Precautions

Binding SIDs are set only on SR-MPLS TE tunnels. If binding SIDs are referenced by an explicit path, they cannot be modified or deleted, and the tunnel type cannot be modified.
