<t>In this document, the use case for L3ND is for point to point

<t>L3DN is intended for use within single IP subnets (IP over
Ethernet or other point-to-point or multi-point IP link) in order to
exchange the data needed to bootstrap BGP-based peering, EVPN, etc.;
often in a datacenter Clos <xref target="Clos"/> environment. Once
IP connectivity has been leveraged to discover1 layer-3
addressability and forwarding capabilities, normal IP forwarding and
routing can take over.</t>
