Troubleshooting MPLS TE
No TE LSA generated
Symptom
OSPF TE is configured but no TE LSAs can be generated to describe MPLS TE attributes.
Analysis
For TE LSAs to be generated, at least one OSPF neighbor must reach the FULL state.
Solution
1. Use the display current-configuration command to verify that MPLS TE is configured on involved
interfaces.
2. Use the debugging ospf mpls-te command to verify that OSPF can receive the TE LINK
establishment message.
3. Use the display ospf peer command to verify that OSPF neighbors are established correctly.
