hey paul, >>> Back in 2021, IEEE 802.1 enhanced LLDP to support the discovery >>> requirements of LSVR. >> uh, did lldpv2 get through the ieee sausage machine yet? i think we >> had a race to see which machine could take the longest :) > The first draft was September 2020. Technical changes were completed > in September of 2021 and it was published in April of 2022. I think > IEEE 802.1 won that race š read again. the race was to see which org could take the *longest*. so the ietf has won! but the contest was not really fair. we practiced; it took the ietf eight years to change the constant 4,096 to 65,535 (see RFC 8654). :) >> as i remember, there were two problems with using lldpv2 in this >> space which l3dl addresses, security and serious scale. has lldpv2 >> managed to move forward on these? truth is, it has all been so long, >> i did not keep my eyes on the ball. > > LLDP itself does not have any inherent security features and that was > never part of its scope. It would be expected to run ontop of MACSec > or people could security their own TLVs using other approaches. to me, this is a show-stopper. this is like the ietf in the old days "no this is not secure. run it over ipsec." it's not the 1990s any more; though i sure wish it was. one of the lessons we have learned over the years is that a protocol designed for the LAN will be deployed on the WAN, and vice versa. heck, this WG is hacking BGP for the LAN :) security is pretty much required these days. > I'm not sure what you mean by serious scale issues. think of a pod with 20 or whatever racks, 40 servers each, and a jillion micro-services on each server. and they want service mobility. observe the serious scale of l3dl. and, with l3dl, there are some *simple* and *efficient* ways to achieve this. randy
