VRRP Attribute

Procedure

   Table 1 describes the parameters on the VRRP Attribute page.

   Table 1 VRRP Attribute

   Parameter	Description
   Ping virtual IP	Indicates whether the ping command can ping the virtual IP address of the VRRP group. The default value is Permit.
   Advertisement packet learning	Indicates whether to enable the function of learning the interval for sending VRRP packets. After this function is enabled, the non-master devices learn the interval for sending VRRP packets and synchronize their timers with the master device. If this function is disabled, VRRP smooth switching is also disabled.
   Smooth switching	Indicates whether to enable VRRP smooth switching. After this function is enabled, the master device sends VRRP packets at the original interval, whereas the VRRP packets contain the interval set by the VRRP packet sending interval parameter. Backup devices learn the interval contained in the VRRP packets. By default, VRRP smooth switching is enabled.
   VRRP packet sending interval	Indicates the interval contained in VRRP packets. NOTE: Generally, the interval carried in the packet must be longer than the originally configured interval. Otherwise, the master device may be busy during the switchover and cannot send VRRP packets in time. As a result, a backup device may become the master device.
   Gratuitous ARP packet sending	Indicates whether to allow the virtual router to send gratuitous ARP packets. To enable the network elements connected to the virtual router to learn the virtual IP address of the VRRP group, the virtual router needs to send gratuitous ARP packets to the network elements. The default value is Permit.
   Gratuitous ARP packet sending interval	Indicates the interval for sending gratuitous ARP packets.
