Bi-directional LSPs [Contention Resolution]

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

Hi All,
        I have a basic doubt regarding contention resolution. The draft
explains the example with upstream label and suggested label. Suggested
label is optional. If a node is not able to allocate the suggested
label then it may override the suggestged label. The actual contention
arises when it is the last label. Am I right ?

Another case, the contention will also occur when say request for
two bi-directional LSPs are initiated in opposite directions and both the 
requests include same upstream label. In addition to this, the label set 
contains one label,  same as upstream label (i.e. sender wants to have 
samelabel in both the directions).

Please clarify.

Regards,
manoj.
