mad ip address

Use mad ip address to assign a MAD IP address to an IRF member device for BFD MAD.
Use undo mad ip address to delete the MAD IP address for an IRF member device.
Syntax
mad ip address ip-address { mask | mask-length } member member-id
undo mad ip address ip-address { mask | mask-length } member member-id
Default
No MAD IP address is configured for an IRF member device.
Views
Management Ethernet interface view, VLAN interface view
Predefined user roles
network-admin
mdc-admin
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
This command is available in management Ethernet interface view in Release 2137 and later
versions.
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.
To avoid problems, only use the mad ip address command to configure MAD IP addresses. Do not
configure an IP address with 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 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.
