Hi Carlos,
after more consideration realized that you have brought up valid concern
and I propose the following change to address it:

   - in section 3.1.1

OLD TEXT

Exactly one sub-TLV MUST be included in the Reverse Path TLV.
   If more than one sub-TLV is present in the Reverse Path TLV, then, in
   order to avoid ambiguity of which of TLVs to use, the egress BFD peer
   MUST send Echo Reply with the received Reverse Path TLVs and set the
   Return Code to "Too Many TLVs Detected" Section 3.2.

NEW TEXT

One or more sub-TLVs MAY be included in the BFD Reverse Path TLV.The
BFD Reverse Path TLV MAY list a stack of FECs that directly
corresponds to the label stack.


   - section 3.2 - remove the first bullet describing return code "Too
Many TLVs Detected"
   - section 5.2 - remove request to allocate return code value for
"Too Many TLVs Detected"


Hope these changes will address your concern.

Regards,

Greg
