MPLS TE configuration task list

To configure an MPLS TE tunnel to use a static CRLSP, complete 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
4. On the ingress node of the MPLS TE tunnel, configure the tunnel interface to reference the created
static CRLSP.
5. On the ingress node of the MPLS TE tunnel, configure static routing or automatic route
advertisement to direct traffic to the MPLS TE tunnel.
To configure an MPLS TE tunnel to use a CRLSP dynamically established by RSVP-TE, complete the
following tasks:
1. Enable MPLS TE and RSVP on each node and interface that the MPLS TE tunnel traverses.
For information about enabling RSVP, see
2. Create a tunnel interface on the ingress node of the MPLS TE tunnel, specify the tunnel destination
address—the address of the egress node, and configure the MPLS TE tunnel constraints (such as
the tunnel bandwidth constraints and affinity) on the tunnel interface.
3. Configure the link TE attributes (such as the maximum link bandwidth and link attribute) on each
interface that the MPLS TE tunnel traverses.
4. Configure an IGP on each node that the MPLS TE tunnel traverses, and configure the IGP to support
MPLS TE, so that the nodes advertise the link TE attributes through the IGP.
5. On the ingress node of the MPLS TE tunnel, configure RSVP-TE to establish a CRLSP based on the
tunnel constraints and link TE attributes.
6. On the ingress node of the MPLS TE tunnel, configure static routing or automatic route
advertisement to direct traffic to the MPLS TE tunnel.
You can also configure other MPLS TE functions such as the DS-TE, automatic bandwidth adjustment, and
FRR as needed.
