5.
Assign the port or the range
of ports to the BFD 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
{
tagged
|
untagged
}
The link type of BFD MAD ports
can be access, trunk, or hybrid.
The default link type of a port is
access.

Enter VLAN interface view.

8.
Enable BFD MAD.
mad bfd enable
By default, BFD MAD is
disabled.
9.
Configure a MAD IP
address for a member
device on the VLAN
interface.
mad ip address
ip-address
{
mask
|
mask-length
}
member
member-id
By default, no MAD IP address
is configured on any VLAN
interface.
The MAD IP address must not
be on the same subnet as any
IP address configured on any
member device.
NOTE:
After a BFD MAD-enabled IRF fabric splits, route conflict messages (for example,
%May 5
16:15:47:733 2010 HPE ARP/3/ROUTECONFLICT: Slot=5;Route conflict found,
IP:192.168.2.1, VrfIndex:0
) might appear on the fabric part that does not have the original
master, because this fabric part still keeps the forwarding entries with the original master as the
destination. This message does not affect forwarding. The system stops generating it after the
forwarding entries are aged out.
Configuring ARP MAD
When you configure ARP MAD, follow these guidelines:
•
If an intermediate device is used, you can use common data links as ARP MAD links. If no
intermediate device is used, set up dedicated ARP MAD links between IRF member devices.
•
Do not use the VLAN configured for ARP MAD for any other purposes.
•
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 an ARP MAD VLAN and assign the ports on the ARP 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.
