direction is established. The CRLSPs of a bidirectional MPLS TE tunnel established in
co-routed mode use the same path.
•
Associated mode—In this mode, you establish a bidirectional MPLS TE tunnel by binding two
unidirectional CRLSPs in opposite directions. The two CRLSPs can be established in different
modes and use different paths. For example, one CRLSP is established statically and the other
CRLSP is established dynamically by RSVP-TE.
For more information about establishing MPLS TE tunnel through RSVP-TE, the Path message, and
the Resv message, see

Restrictions and guidelines for MPLS TE

MPLS TE is mutually exclusive with EVI and VXLAN. For more information about EVI, see EVI
Configuration Guide. For more information about VXLAN, see VXLAN Configuration Guide.

MPLS TE configuration task list

To configure an MPLS TE tunnel to use a static CRLSP, perform the following tasks:
1. Enable MPLS TE on each node and interface that the MPLS TE tunnel traverses.
2. Create a tunnel interface on the ingress node of the MPLS TE tunnel, and specify the tunnel
destination address—the address of the egress node.
3. Create a static CRLSP on each node that the MPLS TE tunnel traverses.
For information about creating a static CRLSP, see
"Configuring RSVP."
