Make sure all the MAD IPaddresses are on the same subnet.Do not configure a MAD IP address by using the ip address command or configure a VRRP virtualaddress on the BFD MAD-enabled port or interface.The master attempts to establish BFD sessions with other member devices by using its MAD IPaddress as the source IP address.• If the IRF fabric is integrated, only the MAD IP address of the master takes effect. The mastercannot establish a BFD session with any other member. If you execute the display bfdsession command, the state of the BFD sessions is Down.• When the IRF fabric splits, the IP addresses of the masters in the partitioned IRF fabrics takeeffect. The masters can establish a BFD session. If you execute the display bfd sessioncommand, the state of the BFD session between the two devices is Up.Examples# Assign a MAD IP address to IRF member 1 on VLAN-interface 3. system-view[Sysname] interface vlan-interface 3[Sysname-Vlan-interface3] mad ip address 192.168.0.1 255.255.255.0 member 1# Assign a MAD IP address to IRF member 2 on VLAN-interface 3.[Sysname-Vlan-interface3] mad ip address 192.168.0.2 255.255.255.0 member 2Related commandsmad bfd enablemad nd enableUse mad nd enable to enable ND MAD.Use undo mad nd enable to disable ND MAD.Syntaxmad nd enableundo mad nd enableDefaultND MAD is disabled.ViewsVLAN interface view
