7.3.2.2.3 LLDPDU transmission, reception, and addressing

The destination address shall be the nearest bridge group MAC address, i.e. 01-80-C2-00-00-0E, to limit the scope of LLDPDU propagation to a single physical link (see IEEE Std 802.1AB‑2016, 7.1 item a).

It is recommended that LLDPDUs be transmitted using the traffic class associated with Network Control as defined in Table 1 and derived from 6.4.3.
