Description Arista MLAG supports STP for Layer-2 loop detection. In fact, most customers enable STP in their MLAG(s) to ensure no downstream Layer-2 loops due to mis-cabling or mis-configuration. Pre 4.25.1F EVPN All-Active multihoming mechanism did not support STP downstream because of the following reasons: Unlike MLAG, EVPN multihoming peers run STP independently. Hence, all EVPN multihoming PEs send BPDUs independently on port-channel links. STP BPDUs will have Bridge ID derived from the local system MAC address, so the BPDUs generated by each multihoming PE are different. Hence, the downstream multihomed switch/server receives different BPDUs from different PEs, so STP...
