Thanks Muthu, Let me add some introduction - PCEP-LS [1] specify a new message, a new object, and some container TLVs but reuses the BGP-LS sub-TLVs inside. It is a particularly good alternative when PCECC [2][3] is in use and for optical networks [4]. Thanks, Dhruv [1] https://datatracker.ietf.org/doc/draft-dhodylee-pce-pcep-ls/ [2] https://datatracker.ietf.org/doc/rfc8283/ [3] https://datatracker.ietf.org/doc/rfc9050/ [4] https://datatracker.ietf.org/doc/draft-lee-pce-pcep-ls-optical/ On Thu, Jun 30, 2022 at 11:30 AM Muthu Arul Mozhi Perumal < muthu.arul@gmail.com> wrote: > Hi, > > A comment inline.. > > On Thu, Jun 30, 2022 at 3:18 AM Susan Hares <shares@ndzh.com> wrote: > >> IDR WG continues to strive to create BGP technology that >> >> a) enables the BGP protocols to solve customer problems, >> >> b) enables implementers to create efficient code, and >> >> c) helps to create a stable and manageable routing infrastructure. >> >> >> >> In our striving, it is sometimes useful to consider >> >> whether a technology can be improved. >> >> In our last WG adoption call for a BGP-LS feature, >> >> the question was raised whether there were better >> >> alternatives to BGP-LS. >> >> >> >> IDR focus is on specific BGP solutions for specific >> >> problems.
