Hierarchy Level


Configure the switch not to respond to gratuitous ARP requests. You can disable responses to gratuitous ARP requests on Layer 2 Ethernet switching interfaces, and integrated routing and bridging (IRB) interfaces or routed VLAN interfaces (RVIs). (On EX Series switches that use Junos OS with support for the Enhanced Layer 2 Software (ELS) configuration style, the feature is known as an IRB interface. On EX Series switches that use Junos OS that does not support ELS, the feature is known as an RVI.)


Gratuitous ARP responses are enabled on all Ethernet switching interfaces, and IRB interfaces or RVIs.
