Multihoming in EVPN allows a single customer edge (CE) to connect to multiple provider edges (PE or tunnel endpoint). In any multihoming EVPN instance (EVI), for each ethernet segment a designated forwarder is elected using EVPN type 4 Ethernet Segment (ES) routes sent through BGP. In single-active mode, the designated forwarder (DF) is responsible for sending and receiving all traffic. In all-active mode, the DF is only used to determine whether broadcast, unknown unicast or multicast packets should be egressed in order to avoid sending multiple copies of the same packet to a CE.
