EVPN ESI Multipath for VxLAN - Flow-based Load Balancing
The EVPN Ethernet Segment Identifier (ESI) Multipath for VxLAN feature supports flow-based load balancing
to forward the traffic between Top of Racks (ToRs) and Data Center Interconnect (DCI), and between the
source and remote DCIs. A flow is identified either by the source and destination IP address of the traffic, or
the source and destination MAC address of the traffic.
In Release 6.2.1, the default load balancing mode is flow-based. You can change the load balancing mode
based on per EVI. See
the load balancing mode based on per EVI.
In Release 6.1.2, only per EVI-based load balancing was supported. Starting from Release 6.2.1, both flow-based
load balancing and per EVI based load balancing are supported. The following table shows the support matrix:

The unknown unicast flooding on traffic received from VxLAN segment is supported. In Release 6.2.1, by
default, the unknown unicast flooding on traffic received from VxLAN segment is enabled. To disable the
unknown unicast flooding, use the suppress-unknown-unicast-flooding command. See
