Figure 14 Recovering the IRF fabric

If the active IRF fabric fails before the IRF link is recovered (see

), use the

mad restore

command on the inactive IRF fabric to recover the inactive IRF fabric. The command also brings up
all network ports that were shut down by MAD. After you repair the IRF link, the two parts merge into
a unified IRF fabric.
