Assign a domain ID to the IRF
fabric
Irf domain domain-id
Required if the intermediate
device is an IRF fabric.
By default, the domain ID of an
IRF fabric is 0.

Required
Use either command.
Enter Layer 3

Configure the aggregation group
to work in dynamic aggregation
mode
link-aggregation mode dynamic
Required
By default, the aggregation
group works in static
aggregation mode.
Enable LACP MAD detection mad enable
Required
Disabled by default.
Even though this command can
be configured on both static and
dynamic aggregate interfaces, it
takes effect only on dynamic
aggregate interfaces. This is
because this detection approach
depends on LACP.

Configuring BFD MAD
1. BFD MAD detection mechanism
BFD MAD is implemented with the BFD protocol. To configure BFD MAD detection, configure a MAD IP
address on a BFD-enabled Layer 3 interface for each member switch. This MAD address identifies the
member during BFD MAD detection. The MAD IP addresses assigned to the member switches must
belong to the same network segment.
• When the IRF fabric is operating normally, only the MAD IP address of the master is effective and
the BFD session is down.
• When the IRF fabric partitions, the MAD IP addresses of the masters in different IRF fabrics become
effective to activate the BFD sessions to detect for multi-active IRF fabric collision.
2. Network requirements
BFD MAD detection can work with or without intermediate switches. In a BFD MAD network without an
intermediate switch, connect all IRF member switches with dedicated BFD MAD links in the full mesh
topology, as shown in Figure 11. T
he interfaces connected by BFD MAD links must belong to the same
