NOTE:
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.
Configuration prerequisites
Before making the configuration, do the following:
Configure static routing or an IGP protocol to make sure that all LSRs are reachable.
•
Configure MPLS basic capabilities.
•
•
Configure MPLS TE basic capabilities.
Configuration procedure
Complete the following tasks to configure an MPLS TE tunnel using a dynamic signaling protocol:
Task
Configuring MPLS TE properties for a link
Configuring CSPF
Configuring OSPF TE
Configuring IS-IS TE
Configuring an MPLS TE explicit path
Configuring MPLS TE tunnel constraints
Establishing an MPLS TE tunnel with CR-LDP
Establishing an MPLS TE tunnel with RSVP-TE
Configuring MPLS TE properties for a link
To configure MPLS TE properties for a link:
Step
1.
Enter system view.
2.
Enter interface view of MPLS
TE link.
3.
Configure maximum link
bandwidth.

By default, RSVP-TE is used for establishing an MPLS
TE tunnel.
