Description
Use
mad bfd enable
to enable BFD MAD.
Use
undo mad bfd enable
to disable BFD MAD.
By default, BFD MAD is disabled.
BFD MAD uses the BFD protocol for detecting multi-active collisions, and can work with or without
intermediate devices.
You can use BFD MAD with ARP MAD, but not with LACP 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.
