> George and I have thrown together a draft that we have been talking  
> about for some time. "Future-Proof TLV Codepoint Space for LSP  
> Ping" (http://www.ietf.org/internet-drafts/draft-farrel-mpls-lsp- 
> ping-tlvs-00.txt) is intended to allow LSP Ping extensions to be  
> backward compatible by defining processing rules for TLVs based on  
> the ranges from which the Type value is allocated. Or, phrased a  
> different way, to set aside two bits from the TLV Type to define  
> the processing rules.
>
> This first version of the draft is pretty rough, but we hope that  
> the ideas will carry forward and gain working group consensus. If  
> so, the main impact would be to update the IANA registry. New LSP  
> Ping TLVs (and sub-TLVs) would then have to indicate the processing  
> rules when the TLV is not understood.

> If you have any questions then please send mail, or corner me or  
> George during the week.
