Static route issue

Hi!

I have two SVI living in my core router. I am using transport link 10.254.1.1 and 10.254.1.2 from Core to Fortigate

Fortigate port1: 10.254.1.2

Fortigate Port2: 10.98.1.200 for management like ssh

SVI on Core 10.254.1.1

SVI 100= 10.100.1.1

SVI 200= 10.98.1.1

If I set the static route like 10.0.0.0/255.0.0.0 next hop via 10.254.1.1 then I can access internet from both SVI's but if I set static route as 10.100.1.0/255.255.255.0 next hop via 10.254.1.1 and 10.98.1.0/255.255.255.0 via 10.254.1.1

then I cannot access the internet from 10.98.1.0 network.

Also from 10.100.1.0 network I cannot reach 10.98.1.200.

If I can set diagnose I can see that syn is arrving on port 22 and same with icmp echo request.

Any tip for it solution?

Thanks
