Used in Massive Data Centers (MDCs), BGP-SPF and similar protocols need link neighbor discovery, link encapsulation data, and Layer 2 liveness. The Link State Over Ethernet protocol provides link discovery, exchanges supported encapsulations (IPv4, IPv6, ...), discovers encapsulation addresses (Layer 3 / MPLS identifiers) over raw Ethernet, and provides layer 2 liveness checking. The interface data are pushed directly to a BGP-LS API, obviating the need for centralized controller architectures. This protocol is intended to be more widely applicable to other upper layer routing protocols which need link discovery and characterisation.
