R3303-HP HSR6800 Routers IRF Command Reference

To avoid problems, only use 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 will 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.

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

Usage guidelines

When MAD detects that an IRF fabric has split into multiple IRF fabrics, only the one whose master has

the lowest member ID among all the masters can still forward traffic. All the other fabrics are set in

Recovery state and cannot forward traffic.

If the active IRF fabric has failed before the IRF split problem is fixed, use this command to restore an IRF

fabric in Recovery state to take over the active IRF fabric role.

Examples

# Restore the normal MAD state of the IRF fabric in Recovery state.

<Sysname> system-view

[Sysname] mad restore

This command will restore the device from multi-active conflict state. Continue? [Y/N]:Y
