MPLS TE configuration task list
To configure an MPLS TE tunnel to use a static CRLSP, perform the following tasks:
Enable MPLS TE on each node and interface that the MPLS TE tunnel traverses.
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.
Create a static CRLSP on each node that the MPLS TE tunnel traverses.
For information about creating a static CRLSP, see "Configuring a static CRLSP."
On the ingress node of the MPLS TE tunnel, configure the tunnel interface to reference the created static CRLSP.
On the ingress node of the MPLS TE tunnel, configure static routing to direct traffic to the MPLS TE tunnel.
To configure an MPLS TE tunnel to use a CRLSP dynamically established by RSVP-TE, perform the following tasks:
Enable MPLS TE and RSVP on each node and interface that the MPLS TE tunnel traverses.
For information about enabling RSVP, see "Configuring RSVP."
Create a tunnel interface on the ingress node of the MPLS TE tunnel, specify the address of the egress node as the tunnel destination address, and configure the MPLS TE tunnel constraints (such as the explicit paths and affinity) on the tunnel interface.
Configure the link TE attributes (such as the affinity attribute) on each interface that the MPLS TE tunnel traverses.
Configure an IGP on each node that the MPLS TE tunnel traverses.
On the ingress node of the MPLS TE tunnel, configure RSVP-TE to establish a CRLSP based on the path calculated by IGP.
On the ingress node of the MPLS TE tunnel, configure static routing to direct traffic to the MPLS TE tunnel.
You can also configure other MPLS TE functions such as bidirectional MPLS TE tunnel and FRR as needed.
