I am building this topology here my PC here should receive ip from central router via DHCP. My PC is on vlan10 and port between switch and office router is trunked on vlan10. DHCP pool is created on central router. office router port fa0/0.10 is on ip 192.168.1.1 and I have configured ip-helper for this port to be 10.0.0.2. But my PC still doesn’t get the ip from central server
