Parameters
ip-address: Specifies an IP address in dotted decimal notation. This IP address is bound to an IRF
member for BFD detection and is called a MAD IP address.
mask: Specifies a subnet mask in dotted decimal notation.
mask-length: Specifies a subnet mask in length, in the range of 0 to 32.
member member-id: Specifies an IRF member ID.
Usage guidelines
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 and are unique among all IP addresses on the IRF fabric.
To avoid problems, only use the mad ip address command to configure MAD IP addresses. Do not
configure a MAD IP address by using the ip address command or configure a VRRP virtual address.
The master attempts to establish BFD sessions with other members by using its MAD IP address as
the source IP address.
•
When 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.
Examples
# Assign a MAD IP address to IRF member 1 on VLAN-interface 3.
<Sysname> 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 2
