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 purposes. • 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. { Enable the IRF fabric to change its bridge MAC address as soon as the master leaves. { Create a 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. False detection causes IRF split. To configure ND MAD: 29

3.
Configure the IRF bridge
MAC address to change as
soon as the master leaves.
undo irf mac-address persistent
By default, the IRF fabric
preserves its bridge MAC
address for 6 minutes after the
master leaves.
4.
Create a VLAN dedicated to
ARP MAD.

The default VLAN on the device
is VLAN 1.

7.
Assign the port to the ARP
MAD VLAN.
•
Assign the port to the VLAN as an
access port:
port access vlan

•
Assign the port to the VLAN as a
trunk port:
port trunk permit vlan

•
Assign the port to the VLAN as a
hybrid port:

ARP MAD detection has no
requirement for the link type of

The default link type of a port is
access.

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 purposes.
•
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.
{
Enable the IRF fabric to change its bridge MAC address as soon as the master leaves.
{
Create a 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. False detection causes IRF split.
