The next-hop IP address traffic uses to reach this tunnel's peer. On a gateway with multiple paths or backup links to the same remote site, this reveals which specific path is currently in use, what an admin checks first when investigating unexpectedly slow or lossy traffic to a site that has both a primary and backup route configured. Example: tunnelNextHop pointing to the backup ISP's gateway rather than the primary one explains a site suddenly experiencing higher latency even though its tunnel state still reports active.
