By default, ARP MAD is
disabled.
Configuring ND MAD
When you use ND MAD, follow these guidelines:
• Do not configure ND MAD on VLAN-interface 1.
• Do not use the VLAN configured for ND MAD for any other purpose.
• If an intermediate device is used, you can use common data links as ND MAD links. If no
intermediate device is used, set up dedicated ND MAD links between IRF member devices.
• If an intermediate device is used, make sure the following requirements are met:
{
Run the spanning tree feature between the IRF fabric and the intermediate device. Make sure
there is only one ND MAD link in forwarding state. For more information about the spanning
tree feature and its configuration, see Layer 2—LAN Switching Configuration Guide.
{
Enable the IRF fabric to change its bridge MAC address as soon as the address owner leaves.
{
Create an ND MAD VLAN and assign the ports on the ND MAD links to the VLAN.
{
If the intermediate device is also an IRF fabric, assign the two IRF fabrics different domain IDs
for correct split detection.
To configure ND MAD:
Step Command Remarks
1. Enter system view. system-view N/A
2. Assign a domain ID to the IRF
fabric.
irf domain domain-id The default IRF domain ID is 0.
3. Configure the IRF bridge
MAC address to change as
soon as the address owner
leaves.
undo irf mac-address persistent
By default, the IRF bridge MAC
address remains unchanged for
6 minutes after the address
owner leaves.
4. Create a VLAN dedicated to
ND MAD.
vlan vlan-id
The default VLAN on the device
is VLAN 1.
5. Return to system view. quit N/A
6. Enter Ethernet interface view
or interface range view.
• Enter interface range view:
{
Method 1:
interface range { interface-type
interface-number [ to
interface-type
interface-number ] } &<1-5>
{
Method 2:
interface range name name
[ interface { interface-type
interface-number [ to
interface-type
interface-number ] } &<1-5> ]
• Enter interface view:
interface interface-type
interface-number
To assign a range of ports to the
ND MAD VLAN, enter interface
range view.
To assign one port to the ND
MAD VLAN, enter Ethernet
interface view.
