ip-address: Specifies an IP address in dotted decimal notation.

mask: Specifies a subnet mask in decimal dotted notation.

mask-length: Specifies a subnet mask in length, in the range of 0 to 32.

member member-id: Specifies the ID of an IRF member.

To use BFD MAD, configure a MAD IP address for each IRF member. Make sure all the MAD IP addresses are on the same subnet.

Do not configure a MAD IP address by using the ip address command or configure a VRRP virtual address on the BFD MAD-enabled port or interface.

The master attempts to establish BFD sessions with other member devices by using its MAD IP address as the source IP address.

If the IRF fabric is integrated, only the MAD IP address of the master takes effect. The master cannot establish a BFD session with any other member. If you execute the display bfd session 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 take effect. The masters can establish a BFD session. If you execute the display bfd session command, the state of the BFD session between the two devices is Up.
