In case the LSP to be created is devoid of any traffic constraints then
the FEC  boils down to only the IP Address.
Otherwise the FEC will additionally contain the traffic parameters also.

Do U mean share this information with other routers ??
I dont think so...

FTN is the mapping between FEC and LSPs and one FEC can
have more than one LSP associated with it.

        This can also be a FEC->TE tunnel head. This
relationship is still possible even if there is no signaled LSP
for the tunnel.

>>4) suggest some reading material on IP routing

Try the itprc.com site..
One Good Book is by "Cristian Huitema".
