Figure 1-3 Cell Network–Ring Topology
Cell Network—Redundant-Star Topology
In a redundant-star topology, every Layer 2 access switch has dual connections to a Layer 3 distribution
switch. Devices are connected to the Layer2 switches. See
Figure 1-4.
• Any Layer 2 switch is always only two hops to another Layer 2 switch.
• In the Layer 2 network, each switch has dual connections to the Layer 3 devices.
• The Layer 2 network is maintained even if multiple connections are lost.
