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 Remarks
Configuring MPLS TE properties for a link Optional.
Configuring CSPF Optional.
Configuring OSPF TE
Required when CSPF is configured.
Choose one depending on the IGP protocol used.
Configuring IS-IS TE
Configuring an MPLS TE explicit path Optional.
Configuring MPLS TE tunnel constraints Optional.
Establishing an MPLS TE tunnel with CR-LDP
Optional.
Use either approach.
By default, RSVP-TE is used for establishing an MPLS
TE tunnel.
Establishing an MPLS TE tunnel with RSVP-TE
Configuring MPLS TE properties for a link
To configure MPLS TE properties for a link:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter interface view of MPLS
TE link. interface interface-type
interface-number
N/A
3. Configure maximum link
bandwidth.
mpls te max-link-bandwidth
bandwidth-value Optional.
0 by default.
