  • Page 5: Setting Up An Irf Fabric

    Setting up an IRF fabric Overview The Intelligent Resilient Framework (IRF) technology virtualizes multiple physical devices at the same layer into one virtual fabric to provide data center class availability and scalability. IRF virtualization technology offers processing power, interaction, unified management, and uninterrupted maintenance of multiple devices.

  • Page 6: Network Topology

    Network topology An IRF fabric can use a daisy-chain or ring topology. IRF does not support the full mesh topology. For information about connecting IRF member devices, see "Connecting IRF physical interfaces." Basic concepts 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.

  • Page 10: Loop Elimination Mechanism

    • The master device fails or is removed. • The IRF fabric splits. • Independent IRF fabrics merge. NOTE: Master election does not occur when two split IRF fabrics merge. Master election selects a master in descending order: Current master, even if a new member has higher priority. When an IRF fabric is being formed, all members consider themselves as the master.

  • Page 11: Mad Mechanisms

    Shuts down all physical network ports in the Recovery-state fabrics except for the following ports: IRF physical interfaces.  Ports you have specified with the mad exclude interface command.  In contrast, BFD MAD, ARP MAD, and ND MAD do not compare the number of members in fabrics. These MAD mechanisms use the following process to hand a multi-active collision: Compare the member IDs of the masters in the IRF fabrics.

  • Page 14 Figure 6 shows a typical BFD MAD scenario that uses an intermediate device. Figure 7 shows a typical BFD MAD scenario that does not use an intermediate device. With BFD MAD, the master attempts to establish BFD sessions with other member devices by using its MAD IP address as the source IP address.
  • Page 15 Figure 8 shows a typical ARP MAD scenario that uses an intermediate device. Each IRF member compares the domain ID and the active ID in incoming extended ARP packets with its domain ID and active ID. • If the domain IDs are different, the extended ARP packet is from a different IRF fabric. The device does not continue to process the packet with the MAD mechanism.

  • Page 21: Specifying A Priority For Each Member Device

    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. A change to member priority affects the election result at the next master election. However, it does not cause an immediate master re-election.

    Configuration prerequisites Make sure the device you are adding to the IRF fabric has sufficient storage space for the new software images. If sufficient storage space is not available, the device automatically deletes the current software images. If the reclaimed space is still insufficient, the device cannot complete the auto-update. You must reboot the device, and then access the Boot menus to delete files.
