Now rebooting, please wait...
Router B reboots to join the IRF fabric. A two-chassis IRF fabric is formed.

ARP MAD-enabled IRF configuration example
Network requirements
Set up a two-chassis IRF fabric at the distribution layer of the enterprise network in
Configure ARP MAD for the IRF fabric and use Router C as an intermediate device. Router C can
come from any vendor.
To prevent loops, enable the spanning tree feature between the IRF fabric and Router C.
