Exports bonded tunnel topology information for specified appliance nePks as a downloadable CSV file. Bonded tunnels aggregate multiple physical underlay tunnels into a single logical connection. The CSV includes source/destination appliance details, tunnel identifiers (tunnelId-A, tunnelId-Z), overlay ID (tunnelSubTypeId), tunnel alias names, HA peer mappings, administrative states, and supporting physical tunnel IDs. Interface-specific fields (Intfc, intfcLabel, intfcIP, edgeHAInterface) are 'n/a' for overlay tunnels since they operate at the logical layer above physical interfaces.
