Recovering an IRF fabric After the failed IRF link between two split IRF fabrics is recovered, log in to the Recovery-state IRF fabric, and use the reboot command to reboot all its members. After these member switches join the Active-state IRF fabric as subordinates, IRF merge is complete, as shown in Figure 11. Figure 11 Recovering the IRF fabric If the Active-state fabric has failed, for example, because of device or link failures, before the IRF link is recovered (see Figure 12), use the mad restore command on the Recovery-state fabric to change its state to Active for forwarding traffic. After you repair the IRF link, the two parts merge into a unified IRF fabric.

Recovering an IRF fabric
After the failed IRF link between two split IRF fabrics is recovered, log in to the Recovery-state IRF fabric,
and use the
reboot
command to reboot all its members. After these member switches join the Active-state
IRF fabric as subordinates, IRF merge is complete, as shown in
Figure 11
.
Figure 11
Recovering the IRF fabric
If the Active-state fabric has failed, for example, because of device or link failures, before the IRF link is
recovered (see
Figure 12
), use the
mad restore
command on the Recovery-state fabric to change its state
to Active for forwarding traffic. After you repair the IRF link, the two parts merge into a unified IRF fabric.
