Accurate path calculation over stretched VLANs without manual gateway selection

NetBrain path calculation currently does not reliably determine the correct traversed path when a VLAN is stretched across multiple sites or devices, unless the user manually specifies the gateway to use. Without manual intervention, the calculated path can diverge from actual traffic flow in these environments. This enhancement would extend the path calculation engine to automatically identify the correct gateway or next hop when tracing across a stretched VLAN topology, removing the need for manual gateway selection. Customers operating stretched VLAN architectures would gain accurate, automatic path visibility, reducing manual verification effort during troubleshooting.
