Usage guidelines
Do not configure ND MAD together with LACP MAD or BFD MAD, because they handle collisions
differently.
Do not configure ND MAD on VLAN-interface 1.
If one IRF fabric uses another IRF fabric as the intermediate device for ND MAD, you must assign
the two IRF fabrics different domain IDs for correct split detection. False detection causes IRF split.
When you use the
mad nd enable
command, the system prompts you to enter a domain ID. If you
do not want to change the current domain ID, press
enter
at the prompt.
An IRF fabric has only one IRF domain ID. You can change the IRF domain ID by using the following
commands:
irf domain
,
mad enable
,
mad arp enable
, or
mad nd enable
. The IRF domain
IDs configured by using these commands overwrite each other.
Examples
# Enable ND MAD on VLAN-interface 3.
<Sysname> system-view
[Sysname] interface vlan-interface 3
[Sysname-Vlan-interface3] mad nd enable
You need to assign a domain ID (range: 0-4294967295)
[Current domain is: 0]: 1
The assigned domain ID is: 1

Usage guidelines
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. The recovered IRF fabric will 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
Restoring from multi-active conflict state, please wait...
