This is a design requirement. Please find the attached two network diagram, one is Logical Diagram (HA Design.pdf) and Other is the Physical wiring of this Logical Design Diagram (HA Design - Physical wiring.pdf)
As you can see all the devices are dual like I have 2 Cisco ASA FW, 2 Cisco 1841 Router, 2 Cisco 3560 L3 switch and 2 Cisco 2960 switch. This is to achieve High Availability in the devices and avoid single point of failures
As refered in Diagram (HA Design - Physical wiring.pdf) is this the way devices has to be connected. If yes, then again there is a single point of failures in the HUB-1 and HUB-2.
I am worried whether I am following the Industry standard for achieving HA Network.
I seek your valuable response and help me on this
