The community makerspace just split its flat network into two segments so the member workstations stop competing with the 3D-print farm. The lease server svc-dhcp01 (10.42.10.8) sits on the services segment (10.42.10.0/24). The new member segment (10.42.20.0/24) hangs off the router EDGE-RTR-7 on interface Gig0/2.

Symptom: the kiosk kiosk-22 on the member segment can't reach anything and shows a 169.254.x.x address. The lease server is healthy and its scope is active. Your job: let the member segment's DHCP request reach the server, then bring the kiosk back online.
