Assign tunnel route priorities

Magic WAN uses a static configuration to route your traffic through Generic Routing Encapsulation (GRE) tunnels from Cloudflare’s edge to your locations

You must assign a route priority to each Anycast GRE or IPsec tunnel–subnet pair in your GRE configuration, as follows:

• Lower values have greater priority.
• When the priority values for prefix entries match—as illustrated by the 103.21.244.0/24 subnet in the example routing configuration (in boldface)—Cloudflare uses equal-cost multi-path (ECMP) packet forwarding to route traffic.

For more on how Cloudflare uses ECMP packet forwarding, see Traffic steering .
