EVPN Multihoming Configuration Guide

introduction introduction evpn multihoming is similar to mc lag and provides support for master/master redundancy when the bgp evpn control plane is used, a host device is connected to two or more access switches evpn esi is configured on downstream interfaces to provide all active redundancy for load balancing and failover basic concepts basic concepts esi esi esi, ethernet segment identifier, 10 bytes when the downlink port of two devices is configured with the same esi, the two ports are the peers of evpn multihoming df election algorithm df election algorithm a designated forwarder selected by the switch for each es is called the df (designated forwarder) correspondingly, devices that have not been elected as df are called non df devices only df is allowed to forward flood traffic received over vxlan overlay to the downlink port with local esi configuration non df devices are not allowed to df election algorithm the evpn vtep with the highest df preference set in the same es will become df the default value of the df preference is 32767 if the preference is the same, the es with the minimum vtep ip address is selected as df the df election is generated by the type 4 route the df election algorithm can solve the remote bum traffic replication problem split horizon algorithm split horizon algorithm split horizon only bum traffic from remote sites is allowed to be forwarded to local sites this algorithm is used to prevent bum traffic loops and replication of the same esi evpn multihoming configuration evpn multihoming configuration table 1 overview of evpn
