Troubleshooting MPLS TE
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) Perform the display current-configuration command to check that MPLS TE is configured on
involved interfaces.
2) Perform the debugging ospf mpls-te command to observe whether OSPF can receive the TE
LINK establishment message.
3) Perform the display ospf peer command to check that OSPF neighbors are established
correctly.
