RSVP and Multi Area OSPF Problem

Hi

I have a large Core network with RSVP running for the LSP setup. But i have
two different OSPF areas for RSVP. THis is my setup

R1---------R2--------R3-------R4------------R5

R1,R2 and R3 are running OSPF area 0 and R3,R4 and R5 are running area 1 .
So in this case R3 is my ABR and i am running RSVP on all the routers .

I have to form a LSP from R1 to R5 . But CSPF runs only within a area and
so the CSPF information will not be passed between areas ( Correct me if i
am wrong )

So how does R1 calculates the path dynamically. Is there any way to do it. ?

I have seen some methods such as Loose and Strict Next hops used in certain
scenarios but i cant really get the point of loose and strict next hops.

What is exactly strict and loose next hops and how many labels it i carries
and how it works.

Has someone in the group tried this scenario.
