Label Distribution Protocol (LDP) defines the following 
name spaces - per [RFCXXXX]

     - Message Type Name Space.
     - TLV Type Name Space.
     - FEC Type Name Space.
     - Status Code Name Space.
     - Experiment ID Name Space.


MESSAGE TYPE NAME SPACE

Message Types 0x0000 - 0x3DFF are part of the LDP base protocol.  
and are allocated through an IETF Consensus action.

Message Types 0x3E00 - 0x3EFF are reserved for Vendor Private 
extensions and are the responsibility of the individual vendors 
(see Section "LDP Vendor-private Messages" of [RFCXXXX]). 
IANA management of this range of the Message Type Name Space 
is unnecessary.

Message Types 0x3F00 - 0x3FFF are reserved for Experimental 
extensions and are the responsibility of the individual 
experimenters (see Sections "LDP Experimental Extensions" and 
"Experiment ID Name Space" of [RFCXXXX]).  IANA management
of this range of the Message Type Name Space is unnecessary;
however, IANA is responsible for managing part of the Experiment
ID Name Space (see below).

TLV TYPE NAME SPACE

TLV Types 0x0000 - 0x3DFF are part of the LDP base protocol.
TLV types in this range are allocated through an IETF Consensus
action.

"LDP Vendor-private TLVs" of [RFCXXX]).  IANA management of this
range of the TLV Type Name Space is unnecessary.

TLV Types 0x3F00 - 0x3FFF are reserved for Experimental extensions
and are the responsibility of the individual experimenters (see
Sections "LDP Experimental Extensions" and "Experiment ID Name 
Space" of [RFCXXXX] ).  IANA management of this range of the TLV
Name Space is unnecessary; however, IANA is responsible for managing
part of the Experiment ID Name Space (see below).

FEC TYPE NAME SPACE

The range for FEC types is 0 - 255.
FEC types in the range 0 - 127 are allocated through an IETF
Consensus action, types in the range 128 - 191 are allocated
