question on GMPLS TE flooding with OSPF

[Anca Zamfir <ancaz@cisco.com>]

Hi,
When a node floods TE link information using OSPF, it needs to fill in the 
neighbor OSPF RouterID as Link ID in the Link TLV. For an optical TE link, 
this node discovers (e.g. using LMP) the neighbor TE Node ID, therefore it 
will need the mapping between the neighbor TE Node ID and the neighbor 
RouterID in order to be able to fill in the required information.
Is a GMPLS node expected to flood the Router TLV only, before the first TE 
Link is configured? If yes, I was not able to find this specified in 
draft-katz-yeung-ospf-traffic-06.txt or 
draft-ietf-ccamp-ospf-gmpls-extensions-07.txt
Or is there another mechanism in place to discover this mapping?
Same questions may be valid for IS-IS.

Thanks,
