Hello I have some basic understanding of Cisco Catalyst SD-WAN, and at work I am now managing a lab/showroom that has Cisco Catalyst SD-WAN as one of the solutions to be demonstraded. However, the design I made is not fully functional, just 1/3 of the tunnels come up.
So I need help with what colors should I use in each WAN interface, and additional settings:
My Setup:
Location 1 (1 Public IP)
1x C8300 -> Site 200 - 3 Uplinks (colors)
1x C8300 -> Site 300 - 3 Uplinks (colors)
2x C8200 -> Site 400 - 2 Uplinks each (colors)
2x C8Kv -> Site 500 - 3 Uplinks each (colors)
Location 2 (10 Public IP)
2x C1131X-4G -> Site 600 - 2 Uplinks each (colors)
2x ISR1100 -> Site 700 - 2 Uplinks each (colors)
2x C8Kv -> Site 800 - 2 Uplinks each (colors)
Graphical view (Current Configuration)

Additional Info:
- I tried using Port Offset for each router.
- In Physical Location 2, each uplink of each site has its own NAT PAT mapped to a Public IP. However, tunnels between sites in this physical location are not coming up, maybe doing to the lack of NAT Hairpinning.
- I am seeing HMAC IPsec errors in the console of routers
- Using carrier option to differentiate private colors between Physical Locations.
