Enabling periodic sending of ND packets for IPv6 VRRP
About periodic sending of ND packets for IPv6 VRRP
This feature enables the master router in an IPv6 VRRP group to periodically send ND packets. Then the downstream devices can update the MAC address entry for the virtual MAC address of the IPv6 VRRP group in a timely manner.
Restrictions and guidelines
This feature takes effect only in VRRP standard mode.
If you change the sending interval for ND packets, the configuration takes effect at the next sending interval.
The master sends the first ND packet at a random time in the second half of the set interval after you execute the vrrp ipv6 send-nd command. This prevents too many ND packets from being sent at the same time.
The sending interval for ND packets might be much longer than the set interval when the following conditions are met:
Multiple IPv6 VRRP groups exist on the device.
A short sending interval is set.
Procedure
Enter system view.

By default, periodic sending of ND packets is disabled for IPv6 VRRP.
