Enabling Mpls Te - HP HPE FlexNetwork MSR Router Series Configuration Manual

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, PBR, 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.
To configure MPLS TE, perform the following tasks:

(Optional.) Configuring a bidirectional MPLS TE tunnel
(Optional.) Configuring CRLSP backup
Only MPLS TE tunnels established by RSVP-TE support this configuration.
(Optional.) Configuring MPLS TE FRR
Only MPLS TE tunnels established by RSVP-TE support this configuration.
(Optional.) Enabling SNMP notifications for MPLS TE

Enabling MPLS TE

Enable MPLS TE on each node and interface that the MPLS TE tunnel traverses.
Before you enable MPLS TE, perform the following tasks:
•
Configure static routing or IGP to ensure that all LSRs can reach each other.
