Figure 2 Two-chassis IRF fabric implementation schematic diagram
In this figure, 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.
You can scale this two-chassis IRF fabric to a four-chassis IRF fabric for higher port density and
availability, as shown in
Figure
3.
