VSI does not go up on S7700 switch

Handling Process
After the configuration is confirmed to be OK and the OSPF session have all been established I have checked the LDP sessions. No LDP sessions have been established although LDP has been activated and anounced in OSPF (lsr-id must be advertised by OSPF).
The reason for this was that the only license file active was the basic one. No MPLS license has been uploaded and thus the MPLS process could be configured but did not start. Afer uploading the correct license file (basic+MPLS license) everything worked like a charm.
Root Cause
In the process of analyzing the cause of this I have first checked the configuration files, the OSPF sessions and then the LDP sessions.
Suggestions
In this kind of situation always check the OSPF session, the LDP sessions and the the license files uploaded.
