vrrp vrid gratuitous-arp copy-to-member

Function

The vrrp vrid gratuitous-arp copy-to-member command enables replication of gratuitous ARP packets for a VRRP group so that when a backup device in the VRRP group assumes the master role, it replicates each gratuitous ARP packet to be sent to each Eth-Trunk member interface.

The undo vrrp vrid gratuitous-arp copy-to-member command restores the default configuration.

By default, this function is disabled. In other words, when a backup device in a VRRP group assumes the master role, it sends a gratuitous ARP packet for each virtual IP address to only one Eth-Trunk member interface.

Usage Guidelines

Usage Scenario

In the scenario where a VRRP group is configured on an Eth-Trunk interface or Eth-Trunk sub-interface, when a backup device in the VRRP group assumes the master role, it sends a gratuitous ARP packet for each virtual IP address to only one Eth-Trunk member interface by default. To ensure that the downstream device can receive gratuitous ARP packets in time and improve network convergence performance, run the vrrp vrid gratuitous-arp copy-to-member command to enable replication of gratuitous ARP packets for a VRRP group so that when a backup device in the VRRP group assumes the master role, it replicates each gratuitous ARP packet to be sent to each Eth-Trunk member interface.

Prerequisites

A VRRP group has been created and assigned a virtual IP address using the vrrp vrid virtual-router-id virtual-ip virtual-address command.The VRRP group has been bound to an mVRRP group in unflowdown mode using the vrrp vrid virtual-router-id1 track admin-vrrp interface interface-type interface-number vrid virtual-router-id2 unflowdown command.

Example

# Enable replication of gratuitous ARP packets for the VRRP group on Eth-Trunk 1 so that when a backup device in the VRRP group assumes the master role, it replicates each gratuitous ARP packet to be sent to each member interface of Eth-Trunk 1.
