Hello Community Members

I am using 2 ISPs: Airtel and N-Tel. Both are on different V-Lans and have their own ONTs. I have one switch as per the mentioned model number. Currently, I have connected the N-Tel ONT to the switch via a LAN cable, and the LAN devices are connected to the N-Tel Network. Wi-Fi, some are using Airtel, and some N-Tel. I want to configure N-Tel and Airtel on the same switch so that, in the event of a failure, another ISP takes over and provides uninterrupted internet to all connected devices. How can I do this? Please guide.

One important point is that both have different Static IPs and the same subnets.
