Configuring BFD MAD
When you configure BFD MAD, follow these guidelines:
Category Restrictions and guidelines
BFD MAD VLAN
• Do not enable BFD MAD on VLAN-interface 1.
• If you are using an intermediate device, assign the ports of BFD MAD links to
the BFD MAD VLAN on the device.
• The IRF fabrics in a network must use different BFD MAD VLANs.
BFD MAD VLAN and feature
compatibility
• Do not use the BFD MAD VLAN for any purpose other than configuring BFD
MAD. Layer 2 or Layer 3 features, including ARP and LACP, cannot 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 will work correctly.
• Disable 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 instance. The
MAD function is mutually exclusive with VPN.
MAD IP address
• To avoid problems, only use the mad ip address command to configure IP
addresses on the BFD MAD-enabled VLAN interface. Do not configure an IP
address with the ip address command or configure a VRRP virtual address on
the BFD MAD-enabled VLAN interface.
• All MAD IP addresses on the BFD MAD-enabled VLAN interface must be on
the same subnet.
To configure BFD MAD:
Step Command Remarks

2. Create a new VLAN
dedicated to BFD MAD
detection.
vlan vlan-id
The default VLAN on the device
is VLAN 1.
3. Return to system view. quit N/A
