Hi Experts,
I need your advice, what do you think if asked to replace the current network router and network firewall with another type of router and firewall.
This is a more or less summary of the current network system:
Head Office
Start -> ISP -> (Firewall) device: Cisco ASA 5515-X -> (Internet Router & WAN Router) devices: Cisco ISR 4331 (2 pcs) -> 2 Core Switch (Juniper) -> Users PC -> End
Branch 1
Start -> ISP -> (Firewall) device: Cisco ASA 5512-X -> (Internet Router) Cisco ISR 4321 -> 2 Core Switch -> Users PC -> End
Branch 2
Start -> ISP -> (Firewall) device: Cisco ASA 5512-X -> (Router) Cisco ISR 4321 -> 2 Core Switch -> Users PC -> End
*Notes: Each site uses a VPN IP (MPLS) service that comes from an ISP provider, to give branch office access to Head Office server.
All devices use Cisco, as well as maintenance and replacement of devices using the services of vendors. The company management wants to save costs by replacing existing devices with other brands, so that maintenance can be carried out by the company's internal IT. Also to replace existing VPN IP subscriptions, by creating a site-to-site VPN over the internet, implemented on new devices.
Now this is the problem,
I stopped at this task, because I am a software engineer and have very little experience about networking. I was asked to learn from scratch and hopefully can handle the task. Also all the IT team doesn't understand Cisco at all, so they don't dare touch the device, let alone do the configuration. Because it's currently being used in production/live operation, it shouldn't experience trouble or downtime.
Please give me your thoughts on this, or insights or advice, I would really appreciate it.
Best Regards,
Antony
