Usage Guidelines

ND multicast suppression can effectively ease the pressure on the gateway in handling NS packets. When receiving an NS request packet, the gateway searches for the host information about the device corresponding to the destination IP address (the IPv6 address and MAC address mapping table of the destination device, also known as the ARP broadcast suppression table).

To display the ND multicast suppression table of a BD, run this command.

Example

# Display the ND multicast suppression table of BD 10.

<HUAWEI> display nd multicast-suppress user bridge-domain 10
