Footnotes

[1] 
The Return Subcode (RSC) contains the point in the label stack where pro-
cessing was terminated. If the RSC is 0, no labels were processed.
Otherwise, the packet was label switched at depth RSC.
[2] 
The Return Code is per "Downstream Detailed Mapping TLV" (Section 3.4). 
This Return Code MUST be used only in the message header and MUST be set 
only in the MPLS echo reply message. If the Return Code is set in the 
MPLS echo request message, then it MUST be ignored. When this Return 
Code is set, each Downstream Detailed Mapping TLV MUST have an 
appropriate Return Code and Return Subcode. This Return Code 
MUST be used when there are multiple downstreams for a given 
node (such as Point-to-Multipoint (P2MP)or ECMP),and the 
node needs to return a Return Code/Return Subcode for 
each downstream. This Return Code MAY be used even 
when there is only one downstream for a given node.
