If you are talking about different VLAN IDs (VIDs) on the same physical interface of an ES is getting mapped to a BD, and the <ES, BD> is advertised via Eth AD per EVI route with Eth-tag of zero, then this is VLAN-bundle service interface. In VLAN bundle, it is assumed that the MAC addresses across different VIDs are unique and thus they all can be placed in a single BD!

When two individual subinterfaces on the same ES are attached to the same BD which is the only one BD (whose Ethernet Tag ID is zero) of its EVI, which Service Interface should the EVI be called? VLAN-based service interface or VLAN-bundle service interface or none of those three service itnerfaces? I noticed that there is just a single A-D per EVI route for that <ES, BD>, thus these two ACs have to share the same A-D per EVI route in such case. So if one of them fails but the other is OK, should that A-D per EVI route be withdrawn or not? When these two interfaces are merged into a single subinterface, I know there is no doubt that this is VLAN-bundle service interface. But here each VLAN has its individual interface. Whether this use case is supported by rfc7432bis? If it is supported, should it be called VLAN-based service interface or VLAN-bundle service interface? Thanks, Yubao
