9.
Enable BFD MAD.
mad bfd enable
By default, BFD MAD is
disabled.
10.
Assign a MAD IP address to
a member device on the
VLAN interface.
mad ip address ip-address

member-id
By default, no MAD IP
addresses are configured on
any VLAN interfaces.
Repeat this step to assign a
MAD IP address to each
member device on the VLAN
interface.
Configuring ARP MAD
Before you configure ARP MAD, choose an ARP MAD link scheme as described in "
As a best practice, connect the ARP MAD links after you finish the ARP MAD configuration if you are
not using existing data links as ARP MAD links.
When you configure ARP MAD, follow these restrictions and guidelines:
Category Restrictions
and
guidelines
ARP MAD VLAN
•
Do not enable ARP MAD on VLAN-interface 1.
•
If you are using an intermediate device, perform the following tasks on
both the IRF fabric and the intermediate device:
{
Create a VLAN and VLAN interface for ARP MAD.
{
Assign the ports of ARP MAD links to the ARP MAD VLAN.
•
Do not use the ARP MAD VLAN for any other purposes.
ARP MAD and feature
configuration
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 to ensure that there is only one ARP 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.
•
If the intermediate device is also an IRF fabric, assign the two IRF fabrics
different domain IDs for correct split detection.
To configure ARP MAD:

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
ARP MAD.

By default, only VLAN 1 exists.
