To configure an MPLS TE tunnel to use a CRLSP dynamically established by RSVP-TE, perform 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. On the tunnel interface,
specify the tunnel destination address (the egress node IP address), and configure MPLS TE
tunnel constraints (such as the tunnel bandwidth constraints and affinity).
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. Then, the nodes can 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.
To configure an MPLS TE tunnel to use a PCE-calculated path to establish a CRLSP, perform 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. Specify an LSR as a PCE and configure an IP address for the PCE.
3. Create a tunnel interface on the ingress node of the MPLS TE tunnel. On the tunnel interface,
specify the tunnel destination address (the egress node IP address), and configure MPLS TE
tunnel constraints (such as the tunnel bandwidth constraints and affinity).
4. Configure link TE attributes (such as the maximum link bandwidth and link attribute) on each
interface that the MPLS TE tunnel traverses.
5. Configure an IGP on each node that the MPLS TE tunnel traverses, and configure the IGP to
support MPLS TE. Then, the nodes can advertise the link TE attributes through the IGP.
6. Configure the ingress node of the MPLS TE tunnel to use the path calculated by the PCE.
Manually specify the PCE or configure OSPF TE to dynamically discover the PCE on the
ingress node (PCC).
7. On the ingress node of the MPLS TE tunnel, configure RSVP-TE to establish a CRLSP based
on the path calculated by the PCE.
8. 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 features such as the DS-TE and FRR as needed.
