Hi Network Engineer experts out there,
I need to refresh our network infrastructure since our network is not secure and not very structured. Right now, our network doesn't have VLANs, everything is VLAN 1. My manager doesn't know much about networking so he couldn't give me any advice at all. Even though I have CCNA but I don't have real experience in networking :). So I just redesign our network. Right now, we have one line for Internet and VoIP from ATT so our network will not be complicated.
My plan is connected our servers to the core layer 3 switch (Router1) and have another layer 3 switch (Router 2) to do VRRP. And have all stack switches connect to core switch. Please look at my diagram and let me know if my topology has any problem or not? Also, I want to install a load balancer but I don't know where should I put it, behind routers/switches or firewall?
Thank you very much. I really appreciated.
