Configuring an IRF fabric
About IRF
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.
IRF network model
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
As shown in Figure 2 , Device A and Device B form a two-chassis IRF fabric. The fabric has four
MPUs (one active and three standbys), and two times the number of interface cards that a single
device provides. The IRF fabric manages the physical and software resources of Device A and
Device B in a centralized manner.
