IRF overview

H3C Intelligent Resilient Framework (IRF) technology creates a large IRF fabric from multiple devices to

provide data center class availability and scalability. IRF virtualization technology offers processing

power, interaction, unified management, and uninterrupted maintenance of multiple devices.

This book describes IRF concepts and guides you through the IRF setup procedure.

Hardware compatibility

An H3C S5130-EI switch can form an IRF fabric only with devices in the same series.

IRF benefits

IRF provides the following benefits:

•Simplified topology and easy management—An IRF fabric appears as one node and is accessible

at a single IP address on the network. You can use this IP address to log in at any member device

to manage all the members of the IRF fabric. In addition, you do not need to run the spanning tree

feature among the IRF members.

•1:N redundancy—In an IRF fabric, one member acts as the master to manage and control the entire

IRF fabric. All the other members process services while backing up the master. When the master

fails, all the other member devices elect a new master from among them to take over without

interrupting services.

•IRF link aggregation—You can assign several physical links between neighboring members to their

IRF ports to create a load-balanced aggregate IRF connection with redundancy.

•Multichassis link aggregation—You can use the Ethernet link aggregation feature to aggregate the

physical links between the IRF fabric and its upstream or downstream devices across the IRF

members.

•Network scalability and resiliency—Processing capacity of an IRF fabric equals the total

processing capacities of all the members. You can increase ports, network bandwidth, and

processing capacity of an IRF fabric simply by adding member devices without changing the

network topology.

Application scenario

Figure 1 shows an IRF fabric that has two devices, which appear as a single node to the upper-layer and

lower-layer devices.

Figure 1 IRF application scenario

Basic concepts

This section describes the basic concepts you might encounter when you work with IRF.

IRF member roles

IRF uses two member roles: master and standby (called subordinate throughout the documentation).

When devices form an IRF fabric, they elect a master to manage and control the IRF fabric, and all the

other devices back up the master. When the master device fails, the other devices elect a new master

automatically. For more information about master election, see "Master election."

IRF member ID

An IRF fabric uses member IDs to uniquely identify and manage its members. This member ID information

is included as the first part of interface numbers and file paths to uniquely identify interfaces and files in

an IRF fabric. For more information about interface and file path naming, see "Interface naming

conventions" and "File system naming conventions."

If two devices have the same IRF member ID, they cannot form an IRF fabric. If the IRF member ID of a

device has been used in an IRF fabric, the device cannot join the fabric.

IRF port

An IRF port is a logical interface for the connection between IRF member devices. Every IRF-capable

device supports two IRF ports. The IRF ports are named IRF-port n/1 and IRF-port n/2, where nis the

member ID of the device. The two IRF ports are referred to as IRF-port 1 and IRF-port 2 in this book.
