Regarding the Error Code TLV: we use that in HVPLS ping, which reuses packet formats from LSP ping. Since it isn't even described in LSP ping, I have no problem with dropping the section. (I will retain the definition in HVPLS ping, unless it gets better defined in LSP ping.) On the other hand, it would be better to have a generic Error TLV defined in LSP ping, rather than in HVPLS ping. -Vach > -----Original Message----- > From: mpls-bounces@lists.ietf.org > [mailto:mpls-bounces@lists.ietf.org] On Behalf Of Adrian Farrel > Sent: Friday, March 18, 2005 11:44 AM > To: mpls@ietf.org; George Swallow > Subject: Re: [mpls] Last Call on "LSP Ping" > > > Hi, > > This is one of the best written I-Ds for a long time! > > A couple of nits. > > Section 4.4 > Note: in all the error codes listed in this draft a > stack-depth of 0 > means "no value specified".
