RFC Editor Note

Section 1. "Conventions used in this document", paras 2 and 3:

OLD:

   If the control and forwarding functions in a router can be
   maintained independently, it is possible for the forwarding function 
   state to be maintained across a control function restart. This 
   functionality is assumed when the terms "restart/restarting" are 
   used in this document. 

   The terms "start/starting" are used to refer to a router in which 
   the control function has either been started for the first time or 
   has been restarted but the forwarding functions have not been 
   maintained in a prior state. 

NEW:

   If the control and forwarding functions in a router can be
   maintained independently, it is possible for the forwarding function
   state to be maintained across a resumption of control function
   operations. This functionality is assumed when the terms 
   "restart/restarting" are used in this document.

   The terms "start/starting" are used to refer to a router in which
   the control function has either commenced operations for the first time 
   or has resumed operations but the forwarding functions have not been
   maintained in a prior state."
