Hi Pablo, I really don't think it is a good idea to use a layer-2 discovery protocol to install routes in the IP(v6) RIB - akin to "bringing a knife to a gun fight". We explicitly avoided installing any routes in https://datatracker.ietf.org/doc/draft-acee-idr-lldp-peer-discovery/ Also, RIPv2

Hi Pablo, It seems like your main justification for attempting to put routing into LLDP is condensed in the below quote from the draft: *"This requires the provisioning of a BGP stack on the host, the configuration * *a BGP session between the host and the leaf router."* Well as you know these d

RFC9131 does for IPv6. LLDP seems to me to be the wrong tool for the job. LLDP support may be common, however ARP and ND are required for all IPv4 or IPv6 implementations (or at least IPv4 implementations post the invention of Ethernet). Regards, Mark. On Fri, 14 Mar 2025, 04:34 Linda Dunbar,

Hi Pablo, Thank you for sharing your insights and ideas with us. It’s great to see the alignment in our thoughts, as we have been working on a similar concept. During the IETF 121 meeting, we presented our idea at SPRING and received valuable feedback from the experts. At the upcoming

Hi all, We have submitted a draft describing an extension to LLDP to allow hosts to advertise their IP prefixes to their attached routers, which can then propagate the reachability of those host prefixes into routing protocols for enabling network-wide connectivity. Any feedback is welcomed.

Hi Pablo, Thanks for sharing. Some time ago we were working on this to mostly address issues in BESS. Niraj was driving this. https://datatracker.ietf.org/doc/html/draft-malhotra-bess-evpn-pe-ce-00 At the time we also discussed whether to define the new TLVs for LLDPv2 or for L3DL, which is t
