You have MPLS1 and MPLS2 links. You want MPLS2 to be the primary path for incoming traffic.

You cannot directly tell the "MPLS2" provider to make it preferred. Instead, you make MPLS1 look "worse" by making its path longer.

• Go to Wan Edge template > Create a Routing Policy named example: Export-MPLS1.
• In the Prepend AS Path field, add your AS number twice: 650XX 650XX. Usually, 2 or 3 prepends are enough to shift traffic. Prepending too many times (e.g., 10+) can lead to route dampening or instability.
• Attach this policy (Export-MPLS1) as an Export Policy to the BGP neighbour group that was created for MPLS1.
• Result: The service Provider sees MPLS2 with a path length of 1 and MPLS1 with a path length of 3. The service Provider will prefer sending traffic to you via MPLS2.
