the range of Ethernet ports
to the specified
aggregation group.
Configuring BFD MAD
When you configure BFD MAD, follow these guidelines:
You cannot enable BFD MAD on VLAN-interface 1.
•
Do not use the BFD MAD VLAN for any other purpose. No Layer 2 or Layer 3 features,
•
including ARP and LACP, can work on the BFD MAD-enabled VLAN interface or any port in the
VLAN. If you configure any other feature on the VLAN, neither the configured feature nor the
BFD MAD function can work correctly.
If a trunk port is assigned to the BFD MAD VLAN, make sure the default VLAN of that port is
•
not used for BFD MAD. If you configure the default VLAN to perform BFD MAD, other services
configured on the port may work abnormally.
Do not enable the spanning tree feature on any port in the BFD MAD VLAN. The MAD
•
function is mutually exclusive with the spanning tree feature.
Do not bind a BFD MAD-enabled VLAN interface to any VPN. The MAD function is mutually
•
exclusive with VPN.
To avoid anomalies, do not use any other command than the mad ip address command to
•
configure IP addresses on the BFD MAD-enabled VLAN interface. For example, an IP address
configured with the ip address command or a VRRP virtual IP address can cause problems.
If an intermediate device is used, assign the ports of the BFD MAD links to the BFD MAD VLAN
•
on the device.
To configure BFD MAD:
Step
1. Enter system view.
2. Assign a domain ID to the
IRF fabric.
3. Create a new VLAN
dedicated to BFD MAD.
4. Return to system view.

The default IRF domain ID is 0.
You can change the IRF domain
ID only in the Admin MDC. The
domain ID setting takes effect
on all MDCs.
The default VLAN on the device
