Alcatel Switch VLAN: Ping Issue

Hello,

I need to set up 2 VLANs. I have two Alcatel 6850 switches.

Here is my config:
Switch 1: Vlan 2 -> 192.168.2.100 -> PC2 192.168.2.1
Vlan 10 -> 192.168.10.100 -> PC1 192.168.10.1

I can ping PC2 from PC1 and vice versa.

Switch 2: Vlan 2 -> 192.168.2.100 -> PC3 192.168.2.3
On this switch, in VLAN 2, I have PC3 and internet coming from my BOX (192.168.2.1)

With PC2, I can ping PC3.
To do this, I set up a trunk port on both switches: vlan 2 802.1q 1/22

But my problem is that from PC1, I can't ping PC3 ....

Looking online, I saw that I need to set a static route on my Switch2:
ip static-route 192.168.10.0 gateway 192.168.2.100

And I get an error message:
ERROR: static routes with gw same as local ip interface address not allowed

I'm stuck here for several days. I've tried setting up OSPF, adding a third switch, etc... But nothing works...

If anyone has a solution, I’m all ears!!

Thanks in advance! :)
