Hello, Section 4.1.1.1 of Rsvp-Lsp-Tunnel-07 (Downstream) states that The downstream node selects a label to represent the flow. If a label range has been specified in the label request, the label MUST be drawn from that range. If no label is available the node sends a PathErr message with an error code of "routing problem" and an error value of "label allocation failure" According to the above mentioned statement, during Resv message processing if a node is unable to allocate a Label should send a Path Error with the above mentioned error code and value. The above statement holds good only for the Egress of the Tunnel. The clarification needed is, whether the intermediate nodes should generate Resv Error or Path Error. Generally the output of any Resv message processing, on success will be a generated Resv message, on failure a Resv Error message.
