Application Scenario; Irf Topologies - HP A5820X Series Configuration Manual

Application scenario

Figure 1 shows an IRF virtual device that comprises two switches, which appear as a single node to the
upper and lower layer devices.

IRF topologies

Create an IRF virtual device in daisy chain topology, or more reliably, ring topology, as shown in
2.
In ring chain topology, the failure of one IRF link does not cause the IRF virtual device to split as in daisy
chain topology. Rather, the IRF virtual device changes to a daisy chain topology without affecting
network services.
