I have two co-operate buildings. Building A is connected to building B via frame relay. Building A has the main switch server (with VLAN info) and a DHCP server. I need Building B devices to receive DHCP IP addresses and client switches to update trunks on VLANs from the server switch. How do I do this over frame relay? Using Cisco Packet Tracer.

    Hello and welcome. You don't say what kind of addressing scheme you're using, nor whether you have any routers. To get DHCP requests from B to server at A, the usual way is with ip helper-address DHCPSERVERADDR on B's router's LAN interface, but that presumes several things about routing and addressing. – jonathanjo Mar 21 at 10:22

    We need to see a diagram of your network as well as relevant device configurations. Most of us here don't have Packet Tracer. – Ron Trunk Mar 21 at 12:19
  • Hello! my setup is DHCP server --> server switch --> edge router A --> Frame Relay --> edge router B --> client switch --> PC DHCP have several pool of net work broadcasting ip on 5 different vlans. I tried using ip helper-address. If i manually put IP on PC in Building B, i can ping all devices including DHCP server in Building A – Orc Man Mar 21 at 13:31
