Usage guidelines

This command ensures that the MAC address entry for the virtual MAC address of an IPv6 VRRP group can be updated on downstream devices in a timely manner.

This command 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.

Examples

# Enable periodic sending of ND packets for IPv6 VRRP and set the sending interval to 200 seconds.
