Yes, if there is no PDU to transmit, we use the keep alive message to 
restart the keep alive timer.

Yes, if the hold timer expires, the LSR deletes the hello adjacency, then 
terminates the LDP session by sending a notification message and closes the 
transport connection ( you can refer to RFC 3036 session 2.5.5. Maintaining 
Hello Adjacencies :-) ).
