Hi Ellen,

If the initial back-off timer is 15 sec , then it follows..... 15 30 60 120 ,...... seconds 
(exponential rise or power of 2 [as in BGP] )

There is no Shutdown msg in LDP, as such. But, it provides a Session Shutdown status code.
So, whenever an LSR needs to send a shutdown msg, it can do  so through Notification msg (with Shutdown status Code)
This is a fatal error msg. So, After sending this notification msg, the LSR should close the transport session and release all the 
label bindings. The receiving  LSR also should close the transport session and release all the label bindings.

Thank you
Ellen
