Can wavelength availability information be carried by OSPF-Ext for GMPLS?

["#SHEN SHU#" <PG03053527@ntu.edu.sg>]

Dear All,

Regarding draft-ietf-ccamp-ospf-gmpls-extensions-07.txt, my understanding is that there's no way to exchange wavelength availability information with such extension. Is this right?
If a LSC router wants to make routing decision based on wavelength availability, how could it collect such information from each link of the network?

Or does the OSPF extension leaves wavelength assignment to LDP completely?

Please comment, thanks!
