2.
Assign a domain ID to the
IRF fabric.
irf domain domain-id
The default IRF domain ID is 0.
3.
Create a Layer 2 aggregate
interface and enter Layer 2
aggregate interface view.

Perform this step also on the
intermediate device.
4.
Configure the aggregation
group to operate in dynamic
aggregation mode.
link-aggregation mode dynamic
By default, an aggregation
group operates in static
aggregation mode.
Perform this step also on the
intermediate device.
5.
Enable LACP MAD.
mad enable
By default, LACP MAD is
disabled.
6.
Return to system view.

To assign a range of ports to
the aggregation group, enter
interface range view.
To assign one port to the
aggregation group, enter
Ethernet interface view.
8.
Assign the Ethernet port or
the range of Ethernet ports
to the specified aggregation
group.

Multichassis link aggregation is
allowed.
Also perform this step on the
intermediate device.
Configuring BFD MAD
Before you configure BFD MAD, choose a BFD MAD link scheme as described in "
."
IMPORTANT:
To avoid the risk of broadcast storms pertinent to full mesh topology, use an intermediate device to
set up BFD MAD if the IRF fabric contains more than two member devices.
As a best practice, connect the BFD MAD links after you finish the BFD MAD configuration.
When you configure BFD MAD settings, follow these restrictions and guidelines:
Category Restrictions
and
guidelines
BFD MAD VLAN
•
Do not enable BFD MAD on VLAN-interface 1.
