This book describes IRF concepts and guides you through the IRF setup procedure. Hardware compatibility An HP 6125XLG blade 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...
Figure 1 IRF application scenario Network topologies An IRF fabric can use a daisy chain topology or a ring topology. Full meshed topology is not supported. For information about connecting IRF member devices, see "Connecting physical IRF ports." Basic concepts This section describes the basic concepts you might encounter when you work with IRF.
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 n is the member ID of the switch. The two IRF ports are referred to as "IRF-port 1" and "IRF-port 2" in this book for simplicity.
Figure 2 A network that comprises two IRF domains Core network IRF 1 (domain 10) Device A Device B IRF link IRF 2 (domain 20) Device D Device C IRF link Access network IRF split IRF split occurs when an IRF fabric breaks up into two or more IRF fabrics because of IRF link failures, as shown in Figure 3.
Figure 4 IRF merge IRF 1 IRF 2 IRF link Device A Device A Device B Device B Member priority Member priority determines the possibility of a member device to be elected the master. A member with higher priority is more likely to be elected the master. The default member priority is 1.

Configuration synchronization mechanism IRF uses a strict running-configuration synchronization mechanism so all chassis in an IRF fabric can work as a single node, and after the master fails, other members can operate correctly. In an IRF fabric, all chassis get and run the running configuration of the master. Any configuration you have made is propagated to all members.
These MAD mechanisms identify each IRF fabric with a domain ID and an active ID (the member ID of the master). If multiple active IDs are detected in a domain, MAD determines that an IRF collision or split has occurred. You can use at least one of these mechanisms in an IRF fabric, depending on your network topology.
If the domain IDs and the active IDs in the extended LACPDUs sent by all the member devices are • the same, the IRF fabric is integrated. If the extended LACPDUs convey the same domain ID but different active IDs, a split has occurred. •...
When the IRF fabric splits, the IP addresses of the masters in the split 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. Figure 6 BFD MAD application scenario Customer premise...

Configuring IRF To ensure a successful IRF setup, read the configuration restrictions and guidelines carefully before you connect and set up an IRF fabric. General restrictions and configuration guidelines Software requirements All IRF member switches must run the same software image version. IRF physical port restrictions and binding requirements To connect blade switches in different chassis into an IRF fabric, you must use the SFP+ and QSFP+ ports on the switch front panel.
Before you bind an SFP+ port to an IRF port or remove it from the IRF port, you must shut down all • the SFP+ ports in the same group. Downlink 10-GE Ethernet port restrictions When you use the downlink 10-GE Ethernet ports on the switch rear panel as IRF physical ports, follow these guidelines: If you use one of the downlink 10-GE Ethernet ports for IRF connection, you must also use all the •...
Save any configuration you have made to the startup configuration file before you reboot the IRF • member devices. Setup and configuration task list HP recommends the basic IRF setup procedure in Figure 9. Perform the tasks in this figure on each member device.
Setup and configuration procedure Remarks HP recommends enabling (Optional.) Enabling software auto-update for software image software auto-update to make sure synchronization system software image synchronization. (Optional.)

Save the priority, save the configuration save configuration.
Figure 10 Connecting IRF physical ports Connect the devices into a daisy chain topology or a ring topology. A ring topology is more reliable (see Figure 1 1). In ring topology, the failure of one IRF link does not cause the IRF fabric to split as in daisy chain topology.

Configuring IRF link load sharing mode On an IRF port, traffic is balanced across its physical links. By default, traffic is distributed automatically based on packet types, including Layer 2, IPv4, and IPv6. You can configure the IRF port to distribute traffic based on certain criteria, including IP addresses, MAC addresses, and any combination of the criteria.

ND MAD • LACP MAD handles collisions in a different way than BFD MAD, ARP MAD, and ND MAD. To avoid conflicts, do not use LACP MAD together with any of those mechanisms. However, you can use BFD MAD, ARP MAD, and ND MAD together. Table 1 provides a reference for you to make a MAD mechanism selection decision.
Configuring LACP MAD When you use LACP MAD, follow these guidelines: • The intermediate device must be a device that supports extended LACP for MAD. If the intermediate device is also an IRF fabric, assign the two IRF fabrics different domain IDs for •...
Configuring BFD MAD When you use BFD MAD, follow these guidelines: Category Restrictions and guidelines • Do not enable BFD MAD on VLAN-interface 1. • If you are using an intermediate device, assign the ports of BFD MAD links to BFD MAD VLAN the BFD MAD VLAN on the device.
Step Command Remarks • Assign the port to the VLAN as an access port: Choose one command port access vlan vlan-id depending on the port type. • Assign the port to the VLAN as a Assign the port or the range BFD MAD has no requirement for trunk port: of ports to the BFD MAD...
