undo arp send-gratuitous enable vrrp 

System view 

None 

Use the arp send-gratuitous enable vrrp command to enable the master switch of a VRRP backup 

group to send gratuitous ARP packets periodically. Upon receiving the gratuitous ARP packets, hosts 

on the network update their respective ARP tables. This can prevent other devices on the network from 

using the same IP address as the VRRP backup group.  

Use the undo arp send-gratuitous enable vrrp command to disable this function. 

By default, this function is disabled. 

Note that: Before enabling the master switch of a VRRP backup group to send gratuitous ARP packets 

periodically, you need to create the VRRP backup group and perform corresponding configurations. 

Refer to the part discussing VRRP in this manual for details.
