Label mapping from targetted peer

Hello all,
I have a question regarding the label mapping procedure(A.1.2) of
rfc3036(LDP).

In Lmp.11,12,13 the next Hop for FEC is checked and if message source is not
the next hop, the label release procedure is executed.

Suppose the peer which sent the label mapping is a targetted peer, then it
will not be the next hop for the FEC but still, it may be a valid mapping if
the mapping has come through the correct next hop interface. So, I think the
check should do more than just compare the message source against the FEC
Next Hop.Going one step further, what to do if there are 2 or more targetted
peers on the same Next Hop interface for the FEC and both of them send
Unsolicited label mappings. How will we decide which to retain and which to
drop?

Please correct me if I am wrong.


Regards,
Vijay
