When you configure BFD MAD that uses management Ethernet ports, follow these restrictions and
guidelines:

Management Ethernet
ports for BFD MAD
BFD MAD VLAN
MAD IP address
Configuring BFD MAD on a VLAN interface
1. Enter system view.
system-view
2. (Optional.) Assign a domain ID to the IRF fabric.
irf domain domain-id
By default, the domain ID of an IRF fabric is 0.
3. Create a VLAN dedicated to BFD MAD.
vlan vlan-id
By default, only VLAN 1 exists.
Do not enable BFD MAD on VLAN-interface 1.
Perform this step also on the intermediate device (if any).
4. Return to system view.

5. Enter Ethernet interface view or interface range view.
Enter Ethernet interface view.

interface interface-type interface-number
Enter interface range view. Choose one of the following commands:

interface range { interface-type interface-number [ to
interface-type interface-number ] } &<1-24>
interface range name name [ interface { interface-type
interface-number [ to interface-type interface-number ] } &<1-24> ]
To assign a range of ports to the BFD MAD VLAN, enter interface range view.
To assign one port to the BFD MAD VLAN, enter Ethernet interface view.
Restrictions and guidelines
configure IP addresses on the BFD MAD-enabled interface. Do not
configure an IP address by using the
configure a VRRP virtual address on the BFD MAD-enabled interface.
•
Make sure all the MAD IP addresses are on the same subnet.
Restrictions and guidelines
Connect a management Ethernet port on each IRF member device to the
common Ethernet ports on the intermediate device. To avoid BFD MAD failure
caused by an active/standby MPU switchover, connect the management
Ethernet ports on each MPU to the intermediate device.
•
On the intermediate device, create a VLAN for BFD MAD, and assign the
ports used for BFD MAD to the VLAN. On the IRF fabric, you do not need
to assign the management Ethernet ports to the VLAN.
•
Make sure the IRF fabrics on the network use different BFD MAD VLANs.
•
Make sure the BFD MAD VLAN on the intermediate device contains only
ports on the BFD MAD links.
•
mad ip address
Use the
command to configure MAD IP addresses on the BFD MAD-enabled
management Ethernet ports.
•
Make sure all the MAD IP addresses are on the same subnet.
