Hi!

I believe you may misunderstand the definition of Broadcast domain (BD) and bridge table( as known as bridge domain).

6.2<https://tools.ietf.org/html/rfc7432#section-6.2>. VLAN Bundle Service Interface

   With this service interface, an EVPN instance corresponds to multiple
   broadcast domains (e.g., multiple VLANs); however, only a single
   bridge table is maintained per MAC-VRF, which means multiple VLANs
   share the same bridge table.

Best regards,

Frank

Yes, This errata should be rejected because VLAN-bundle service requires ONLY a single BD - that is analogous to SVL mode in 802.1Q. It is VLAN-aware bundle service that requires multiple BDs!

Cheers,
Ali
