Route traffic from one VPN tunnel to the other

RouterOS Beginner Basics
1

Hi there,

I have three sites with the following interconnections:
Site1 connected to Site2 and Azure site
Site2 connected only to Site1

I need to establish a route that goes from Site2 to Azure through Site1. I’m using RouterOS 6.20 on Site1 and SonicWall on Site2.

Any ideas?

You could implement ospf routing.

Can you show me some example?
