Hi bob,

[1] In that case why Label Release Message in 3.5.11 does not contain
Status TLV as
optional parater. For that matter, accroding to 3.4.6 last para every
message should
have Status TLV as optional.
shouldn't this be updated in the rfc.

[2] In section 3.5.11 Label Release Message and 3.5.10 Label withdraw
message - Label
TLV (optional) field is present as well as in the optional parameters
list Label TLV is
present. Is this wrong or does it have any implicit meaning..... ????

Thanks in advance
Amar
