Configuring ND MAD
ND MAD can use only common Ethernet ports.
When you use ND MAD, follow these restrictions and 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 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:

Remarks
1.
Enter 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.

The default VLAN on the device
is VLAN 1.

Assign the port to the ND
MAD VLAN.
•
Assign the port to the VLAN as
an access port:
port access vlan
vlan-id
•
Assign the port to the VLAN as a
trunk port:
port trunk permit vlan vlan-id
•
Assign the port to the VLAN as a
hybrid port:
port hybrid vlan vlan-id

The link type of ND MAD ports
can be access, trunk, or hybrid.
The default link type of a port is
access.
