Usage guidelines

Do not configure ND MAD together with LACP MAD, because they handle collisions differently.

Do not configure ND MAD together with BFD MAD. ND MAD requires the spanning tree feature, but BFD MAD is mutually exclusive with the spanning tree feature. At the same time, ND MAD handles collisions differently than BFD MAD.

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.

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.

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
