Basic Core Topology shows a core topology with two access rings. In this topology, there are two EAPS (Extreme Automatic Protection Switching) common links.
In the right-angle topology, there are still two EAPS common links, but the common links are adjacent to each other.
To configure a right-angle topology, there must be two common links configured on one of the switches. Right-Angle Topology shows a right-angle topology.
Basic Core and Right Angle Topology shows a combination basic core and right-angle topology.
Advanced Basic Core and Right Angle Topology shows an extension of the basic core and right angle configuration.
Large Core and Access Ring Topology shows a single large core ring with multiple access rings hanging off of it. This is an extension of a basic core configuration.
