Configuring BFD MAD
When you use 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 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.
• Disable the spanning tree feature on any Layer 2 Ethernet ports 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.
