Figure 16 Recovering the IRF fabric
If the active IRF fabric fails before the IRF link is recovered (see Figure 17 ), use the mad restore command
on the inactive IRF fabric. This command changes the MAD state of the inactive IRF fabric to Detect and
brings up all physical interfaces that were shut down by MAD. After you repair the IRF link, the two parts
merge into a unified IRF fabric.
