The following subsections describe several H3C recommended IRF connection schemes, and all these
schemes use a ring topology.
Connecting the IRF member switches in one rack
Use short-haul and long-haul SFP+ cables to connect the IRF member switches (10 switches in this
example) in a rack as shown in Figure 70 . The switches in the ring topology (see Figure 71 ) are in the
same order as connected in the rack.
