The Cisco implementation puts the ingress node's ip address in this field.

The two spaces are independent.  In fact LSP ID need only be unique within the scope 
of a particular tunnel.  So you could always set LSP_ID = Tunnel_ID if there were only
one LSP associated with the tunnel for all time.  But they are different identifiersm so I wouldn't
call them the "same", they just happen to have the "same value".
