Configuring An Mpls Te Tunnel With A Dynamic Signaling Protocol; Configuration Prerequisites - HP 10500 SERIES Configuration Manual

Step
2. Enter the interface view of an
MPLS TE tunnel.
3. Configure the tunnel to use
static CR-LSP.
4. Submit
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.
•
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.
To form a TEDB, 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.

Configuration prerequisites

Before you perform the configuration, complete the following tasks:
Configure static routing or an IGP protocol to make sure all LSRs can reach each other.
•
• Configure basic MPLS.
