ARP Suppression for BGP EVPN Overview

Address Resolution Protocol (ARP) suppression reduces the flooding of ARP messages in the BGP EVPN network, leading to a more efficient use of core bandwidth. ARP suppression can be enabled for an EVPN instance. For BGP EVPN, when a VLAN is mapped to a VXLAN VNI, ARP suppression extends to corresponding EVPNs, VNIs, and EVIs. When ARP suppression is enabled, snooping MAC-IP bindings of any local endpoints for that VLAN is enabled.

  1. ARP Suppression for BGP EVPN Overview
    Address Resolution Protocol (ARP) suppression reduces the flooding of ARP messages in the EVPN network, leading to a more efficient use of core bandwidth.
  2. Configuring ARP Suppression for BGP EVPN
    You can enable ARP suppression for an EVPN instance. For BGP EVPN, when a VLAN is mapped to a VXLAN VNI, ARP suppression extends to corresponding EVPNs, VNIs, and EVIs. When ARP suppression is enabled, snooping MAC-IP bindings of any local endpoints for that VLAN is enabled. The information is maintained in a per-VLAN MAC-IP table. In addition to MAC-IP bindings learned through ARP snooping, any MAC-IP bindings learned via the BGP EVPN control plane are also stored in the same MAC-IP table.
