It is a design related query. Please find the attached Diagram.
I have 2 firewall & 2 Routers & 2 Switches to be operated in redundancy.
My customer is asking connected the cables and configure the setup as shown in the diagram marked with yellow colour. Now to achieve this I have used a Layer 2 switch to connect the cables between Firewall and Router and another Layer 2 switch to connect the cables between the firewall and Switches.
Is this is a best practice and only option to connect the Devices in this fashion (as shown as Yellow colour in the Diagram attached). Wont it bring the latency or Single point of failure??
Expecting your help in clarifying this concept
