# Exclude GigabitEthernet 2/3/0/1 from being shut down when the MAD status transitions to

Recovery.

<Sysname> system-view

[Sysname] mad exclude interface gigabitethernet 2/3/0/1

mad ip address

Use mad ip address to assign a MAD IP address to an IRF member on a VLAN interface for BFD

MAD.

Use undo mad ip address to delete a MAD IP address.

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 on any VLAN interface.

Views

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

To use BFD MAD, configure a MAD IP address on a BFD MAD-enabled VLAN interface for each IRF

member, and make sure all the MAD IP addresses are on the same subnet.

To avoid anomalies, do not use any other command than the mad ip address command to

configure IP addresses on the BFD MAD-enabled VLAN interface. For example, an IP address

configured with the ip address command or a VRRP virtual IP address can cause problems.

The master tries to establish BFD sessions with other members 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, and 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, and the two 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.
