Figure 27 - Parallel Redundancy Protocol (PRP) Topology
PRP provides a redundant network infrastructure. An important feature of
PRP is that the two LANs do not meet, but connect at the PRP end nodes. An
end node that is connected to both LANs is called Doubly or Dually Attached
Nodes or DANs. Both terms are fully accepted and used in the IEC standard.

IMPORTANT
Never connect LAN A and LAN B directly to each other. For example, never
connect an infrastructure switch in LAN A to an infrastructure switch in
LAN B.
Also, be sure that each device in LAN A and LAN B has a unique IP address.
