That’s not correct.  The service in question assumes that there are multiple VLANs but that a given MAC address is unique across all of them.  Hence, one broadcast domain.

Concur, this erratum 5899 should be rejected.

Erratum 5900<https://urldefense.com/v3/__https://www.rfc-editor.org/errata/eid5900__;!8WoA6RjC81c!UGrmlwynsVF22uakunYYqBVrii_3PWz4Q43L2WbuaSCoKttHoPEA3FhjNypHO7k$> makes somewhat more sense, VLAN Bundle in 7432 6.2 is for multiple broadcast domains, so switching "VLAN Bundle services" to "multiple BDs" makes sense. Nit.
