Explicit Label Control

["manoj juneja" <manojkumarjuneja@hotmail.com>]

Hi All,

In GMPLS and O-UNI drafts, the concept of Egress/explicit Label control is 
described. Is this valid only at egress or intermediate nodes also ? I have 
gone through both the GMPLS and O-UNI drafts. The O-UNI draft clearly 
describes it as Egress Label i.e. label to be used at destination UNI. But 
GMPLS describes the term Explicit Label object. The GMPLS draft mentions 
that the explicit label subobject can be present anywhere (as per my 
understanding) in ERO provided that this sub-object should follow a 
subobject containing the IP address or interface identifier (strict object).
I mean to say whether the Explicit Label object will only be at the
end of ERO or it can appear in between in case of GMPLS ?

Please clarify.

Regards,
manoj.
