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 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.
Usage guidelines
To use BFD MAD, configure a MAD IP address on a BFD MAD-enabled VLAN interface for each IRF
member. Make sure all the MAD IP addresses are on the same subnet.
To avoid problems, only use the
mad ip address
command to configure IP addresses on the BFD
MAD-enabled VLAN interface. Do not configure an IP address by using other commands (for example,
the
ip address
command) on the BFD MAD-enabled VLAN interface.
The master tries 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 is effective. 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
