Need Advice in Dual-Hub Dual ISP Topology

Dear All,

I have made one or two topics a few weeks ago on how to get this topology working, and finally I have completed it ( yet I think so.. ).

There are 2 Networks on my spokes, DATA and INTERNET.

DATA network is always most important, and INTERNET is least.

What I have achieved is , DATA will always use HUB1 as its primary Hub, because it's more reliable and I wanted to centralize each network within one Hub instead of load balancing between two Hub's.Because ISP2 is less reliable, I made it so DATA will always use ISP1 if possible, while INTERNET always goes through ISP2 if possible to reduce the load on ISP1.

I need some recommendation from other people too because I haven't seen anyone else with the same or similar configuration to get this working.Thats why i'm not so sure if this configuration should work fine when it comes to production.

Note : This was all simulated in my Lab environment , and it SHOULD work the same way in production, since its the same topology there too.I have also changed all the IP addresses , so the configs might not be suitable for Copy Paste and needs editing.

Thanks all, and I appreciate everyones contribute.

Here's a screenshot of my Lab:

IP Addressing:

Spoke:

DATA : 200.100.100.0/24

INTERNET: 200.101.100.0/24

ISP1: 192.168.28.18/30  - gw 192.168.28.17.

ISP2: 111.111.111.100/24  - no gw needed because its Layer 2 VPN.

Hub1:

T0 : 100.100.100.1/24

T1 : 100.100.101.1/24

ISP1: 192.168.28.249/29 - gw 192.168.28.254.

ISP2: 111.111.111.1  - no gw needed because its Layer 2 VPN.

Hub2:

T0 : 100.100.200.1/24

T1 : 100.100.201.1/24

ISP1 : 192.168.28.250/29 - gw 192.168.28.254

ISP2 : 111.111.111.2/24  - no gw needed because its Layer 2 VPN.

Stack Switch:

Simulated networks on Vlan interfaces:

100.140.2.1/24

100.140.3.1/24

100.200.200.1/24
