Refer to the exhibit. The operations team is implementing a route-map policy. Traffic from source 192.168.30.1 must reach the customer network 192.168.1.1 via the secondary link R4-R6-R5. All other…

Applying a route-map 'in' on R6 with R5 BGP peering would affect how R6 receives routes from R5, but it would not influence R4's decision on how to forward traffic towards 192.168.1.1/32 from the data center.

Applying a route-map 'out' on R3 with R4 BGP peering would affect what R3 advertises to R4, but the goal is to influence R4's path selection for traffic originating from the data center to a specific destination, which is better done by modifying R4's received routes.

Applying a route-map High-LP on R6 with R4 BGP peering would increase the Local Preference for routes R6 learns from R4, which is the opposite of what's needed to make R4 choose a path via R6 over R3 for specific traffic.

Applying a route-map with a Low-LP (Local Preference) 'in' on R4's BGP peering with R3 allows R4 to reduce the Local Preference for the specific prefix 192.168.1.1/32 when it learns it from R3. This makes R4 prefer the path to 192.168.1.1/32 learned from R6 (secondary link) instead, because BGP prefers paths with a higher Local Preference.
