When the IRF stack is up, you should configure MAD (Multi-Active Detection) mechanism. MAD is used to prevent from duplicating IP addresses on switches if the IRF links go down. With MAD active and IRF links down the second switch won’t respond to pings although it would have the duplicate IP address. If MAD link is broken then the duplicate IP address on the second switch will respond resulting in network integrity corruption. To prevent such a behavior use MAD. There are three kinds of MAD realisation. We will use BFD MAD. For BFD MAD we will not need the third device for it function but we will need an additional link from both switches.
