False detection causes IRF split.When you use the mad nd enable command, the system prompts you to enter a domain ID. If youdo 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 followingcommands: irf domain, mad enable, mad arp enable, or mad nd enable. The IRF domainIDs configured by using these commands overwrite each other.Examples# Enable ND MAD on VLAN-interface 3. system-view[Sysname] interface vlan-interface 3[Sysname-Vlan-interface3] mad nd enableYou need to assign a domain ID (range: 0-4294967295)[Current domain is: 0]: 1The assigned domain ID is: 1Related commandsirf domainmad restoreUse mad restore to restore the normal MAD state of the IRF fabric in Recovery state.Syntaxmad restoreViewsSystem viewPredefined user rolesnetwork-adminUsage guidelinesIf the active IRF fabric has failed to work before the IRF split problem is fixed, use this command torestore an IRF fabric in Recovery state.
