Hi Abhishek,

being used by this tunnel instance.

Ya , you are right . But would not the values of the two indexes be the same
for any tunnel instance , as Abhay also pointed out . If two indexes have
the same value , wouldn't that mean a duplication ? Or is that the Hop Table
could look like this :

HopListLindex  PathOptionIndex HopIndex [ Hop Details ]
	1			1              1		ERO1
	1			1              2                   ERO1
	1			1	    3                   ERO1
	1			2              4                   ERO2
	1			2              5                   ERO2
	1			2              6                   ERO2
	1			2              7                   ERO2

	where the ERO1's denote the subobjects of the primary ERO
	and ERO2's denote the subobjects of the secondary ERO ?

	In the normal case then HopListIndex = PathOptionIndex always and
also HopListIndex is a misleading name as it is the index to TWO hop lists
and is not an unique identifier of a Hop List .

	Thanks
