Usage guidelines
ND MAD uses extended NS packets of the IPv6 ND protocol to detect multi-active collisions.
Do not configure ND MAD together with LACP MAD, because they handle collisions differently.
Do not configure ND MAD together with BFD MAD if common Ethernet ports are used for BFD MAD.
ND MAD requires the spanning tree feature, but BFD MAD is exclusive with the spanning tree
feature.
Do not configure ND MAD on VLAN-interface 1.
You can set up ND MAD links between neighbor IRF member devices, or between each IRF member
device and an intermediate device.
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.
NOTE:
• 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.
• You can execute the mad nd enable command on any MDCs. If you change the IRF domain ID
in one MDC, the new IRF domain ID takes effect immediately on all MDCs.
