In the following configuration example, PE-70 and PE-73 are part of the same single-active multihoming, Ethernet-segment ESI-7413. In this case, the CE is connected to PE-70 and PE-73 through spoke-SDPs 4:74 and 34:74, respectively.
In this example PE-70 and PE-73 use a different source-bmac for packets coming from ESI-7413 and it is not an es-bmac as shown in the PBB-EVPN all-active multihoming example.
