The instance type 'virtual-switch' supports under hierarchy:
Statement introduced in Junos OS Release 17.2R1 for MX Series routers and EX Series switches.
Statement introduced in Junos OS Release 17.3R1 for QFX Series switches.
Support for logical systems on MX Series routers added in Junos OS Release 17.4R1.
Statement deprecated in Junos OS Release 19.1R1 for all devices and all following releases.
Disable the suppression of Address Resolution Protocol (ARP) requests from a customer edge (CE) device or Layer 2 VXLAN gateway to a provider edge (PE) device or Layer 3 VXLAN gateway that acts as ARP proxy in an Ethernet VPN-MPLS (EVPN-MPLS) or Ethernet VPN-Virtual Extensible LAN (EVPN-VXLAN) environment.
When disabling ARP suppression, be aware of the following implications;
If the PE device or Layer 3 VXLAN gateway does not find the MAC-IP address binding in its database, it cannot forward the ARP request. Instead, the device discards the ARP request, and the packets flood through the Layer 2 domain because the ARP request is considered to be Layer 2 broadcast traffic.
Disabling the suppression of ARP packets on a PE device or Layer 3 VXLAN gateway essentially disables the proxy ARP functionality.
Therefore, we recommend that ARP suppression remains enabled.
