The liaison should go to IEEE 802.1.

> Used in Massive Data Centers (MDCs), BGP Link-State Shortest Path First (BGP-SPF) produced in LSVR and similar protocols need a mechanism for link neighbor discovery, link encapsulation data, and Layer 2 and Layer 3 liveness. The BGP-SPF base protocol (https://datatracker.ietf.org/doc/draft-ietf-lsvr-bgp-spf/) does not standardize a discovery and liveness technology, however in some scenarios it relies on such technology.  The Layer-3 Discovery and Liveness (L3DL) protocol provides link discovery, exchanges endpoint and interface identifiers (IPv4, IPv6, ...), discovers supported encapsulation information (Layer 3, Layer 2.5) over Ethernet, provides layer 2 liveness checking, enable layer 3 liveness checking and exchange parameters needed for upper layer protocol configuration. The development of L3DL is initially focused around the BGP-SPF requirements for operation in MDCs.
> The L3DL protocol used to be named as LSoE (Link State over Ethernet), on which a liaison was sent on January 10, 2019 (https://datatracker.ietf.org/liaison/1621 <https://datatracker.ietf.org/liaison/1621/>). Early this year, L3DL is added as the deliverable of the LSVR WG's charter https://datatracker.ietf.org/doc/charter-ietf-lsvr, and the WG plans to initiate the WG LC for this document soon. We anticipates that there will be ongoing discussion of this topic at the IETF's meeting in Bangkok during the week of March 16, 2025.
> At this stage we welcome your views on the L3DL draft, and welcome your participation in the WG Last Call on the LSVR WG's mailing list ([e-mail] <mailto:[e-mail]>). More specifically, this document has one section on IEEE considerations, your feedback on that is much appreciated.
