Configuring An Mpls Te Tunnel With A Dynamic Signaling Protocol - HP HSR6800 Configuration Manual

Step
1. Enter system view.
2. Enter the interface view
of an MPLS TE tunnel.
3. Configure the tunnel to
use static CR-LSP.
4. Submit the current tunnel
configuration.
5. Return to system view.
6. Create a static CR-LSP.
Configuring an MPLS TE tunnel with a dynamic
signaling protocol
Dynamic signaling protocol can adapt the path of a TE tunnel to network changes and implement
redundancy, FRR, and other advanced features.
The following describes how to create an MPLS TE tunnel with a dynamic signaling protocol:
•
Configure MPLS TE properties for links and advertise them through IGP TE extension to form a
TEDB.
To form a TEDB, you must configure the IGP TE extension for the nodes on the network to send
TE LSAs. If the IGP TE extension is not configured, the CR-LSP is created based on IGP
routing rather than computed by CSPF.
•
Configure tunnel constraints.
•
Use the CSPF algorithm to calculate a preferred path based on the TEDB and tunnel
constraints.
•
Establish the path by using the signaling protocol RSVP-TE or CR-LDP.
