I am working on to design a network for small office and due to present limitations only 1 WAN router with 1 ISP is in place now, but LAN has 2 core switches with HSRP for all VLANs.
At present only core1 is connected to WAN router with the static route and there are no dynamic routing in core switches.
I am planning to connect to the WAN router from core 2 switch as well to achieve the failover in case core 1 fails.
All the devices are Cisco devices.
Question: What are the best available solution to this topology considering the limitations of no dynamic routing in cores and only 1 WAN with 1 ISP?
Thanks in Advance!
