When the IRF fabric is integrated, only the MAD IP address of the master is effective, and the master
cannot establish a BFD session with any other member. If you execute the
display bfd session
command, the state of the BFD sessions is
Down
.
•
When the IRF fabric splits, the IP addresses of the masters in the partitioned IRF fabrics take effect,
and the two masters can establish a BFD session. If you execute the
display bfd session
command,
the state of the BFD session between the two devices is
Up
.
Examples
# Assign a MAD IP address to IRF member 1 on VLAN-interface 3.
<Sysname> system-view
[Sysname] interface vlan-interface 3
[Sysname-Vlan-interface3] mad ip address 192.168.0.1 255.255.255.0 member 1
# Assign a MAD IP address to IRF member 2 on VLAN-interface 3.
[Sysname-Vlan-interface3] mad ip address 192.168.0.2 255.255.255.0 member 2

Description
Use
mad restore
to restore the normal MAD state of the IRF fabric in Recovery state.
When MAD detects that an IRF fabric has split into multiple IRF fabrics, it sets one of the IRF fabrics to the
Detect state and other IRF fabrics to the Recovery state.
•
The Detect-state IRF fabric is active and can continue to forward traffic.
•
The Recovery-state IRF fabrics are inactive. MAD shuts down all their physical ports except the IRF
ports and the ports manually configured to not shut down.
If the active IRF fabric has failed to work before the IRF split problem is fixed, use this command to restore
an IRF fabric in Recovery state to take over the active IRF fabric role.
Examples
# Restore the normal MAD state of the IRF fabric in Recovery state.
<Sysname> system-view
[Sysname] mad restore
This command will restore the device from multi-active conflict state. Continue? [Y/N]:Y
