IRF topologies
Create an IRF virtual device in daisy chain topology, or more reliably, ring topology, as shown in Figure
2.
In ring chain t
opology, 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.
