ARP-Based Next Hop Resolution in Standard Path Calculation

NetBrain path calculation currently cannot distinguish between two devices that share identical IP configuration, such as a production device and its disaster recovery counterpart, unless the L3 Active path calculation option is enabled. Without that option, the calculation may present a path to a device that does not actually carry the traffic, since it relies on IP-based matching rather than the ARP-derived MAC address that identifies the true next hop. This enhancement would extend the default path calculation logic to check ARP table entries on the previous hop device and use the resolved MAC address to identify the correct next hop, applying this logic even when L3 Active path calculation is not selected. Customers with redundant or DR device pairs sharing the same IP addressing would gain accurate path visualization without needing to enable a more resource-intensive calculation option, reducing troubleshooting time and improving confidence in the displayed path.
