Because R1 and R4 in different OSPF area, so it must disable cspf when creating RSVP path between R1 and R4 in LSP ingress and egress, check RSVP session state

In order to use the special LSP to destination, create nex-hop policy in ingress,
In this case R1 To R5 will use r1-r4 LSP and R1 To R6 will use r1-r4-prime LSP
