GRE TUNNEL TUNNEL GETTING PRECEDENCE OVER OSPF

KEITH ZONGORO

Hello, 

I'm currently managing an XGS Sophos firewall at our headquarters, and we have a dual ISP setup connecting to branch offices. Our primary ISP uses **OSPF**, while the secondary ISP relies on a **GRE tunnel.

The challenge arises when I add a route to the GRE tunnel: traffic starts flowing through ISP2, which is not the desired behavior. My goal is to configure failover so that when ISP1 fails, ISP2 automatically takes over.

Could anyone provide guidance on how to set up OSPF to take precedence over the GRE tunnel on our XGS Sophos firewall? I want to ensure seamless failover while maintaining efficient routing.


Thank you in advance for your insights!
