R3303-HP HSR6800 Routers IRF Configuration Guide

Planning the IRF fabric setup

Consider the following items when you plan an IRF fabric:

• Hardware compatibility and restrictions

• IRF fabric size

• Master device

• IRF physical ports

• Member ID and priority assignment scheme

• Fabric topology and cabling scheme

For more information about hardware and cabling, see the installation guide for the device.

Preconfiguring IRF member devices in standalone

mode

Perform the tasks in this section on every IRF member device. These settings take effect on each member

device after their operating mode changes to IRF.

Assigning a member ID to each IRF member device

A device by default operates in standalone mode without an IRF member ID. You must assign it a unique

IRF member ID before changing its operating mode to IRF.

Execute the display irf configuration command and examine the MemberID field. If the device has no IRF

member ID, the field displays two hyphens (--).

The member ID assigned to a device is saved in both active and standby MPUs of the device. If the

standby MPU has a different member ID than the active MPU, for example, because of an MPU

replacement, the member ID in the active MPU takes effect and is automatically updated to the standby

MPU.

To set a member ID for the device in standalone mode:

By default, the device has no IRF

member ID.

Specifying a priority for each member device

IRF member priority represents the possibility for a device to be elected the master in an IRF fabric. The

higher the priority, the higher the possibility.

To specify a priority for the device:
