In my network topology, I have 4 devices 2 router and 2 end devices. On gateway I have 2 NIC, one NAT and one LAN (GW_LAN). Also, gateway is configured as DHCP Server. On router, I have 2 NIC, one LAN (GW_LAN) from gateway and one LAN (RTR_LAN) for another network. The router is configured as "DHCP Relay Agent". One of the end device have static IP address. Also, end device with static IP is configure as "DHCP Relay Agent" Another end device will get IP from DHCP Server. My confusion is how to forward DHCP Request with two DHCP Relay agents. Do we configured DHCP Relay agent as follow?

SERVERS="dhcp-server-ip-address"

INTERFACES="eth1 eth2 10.0.0.1"

for interfaces, do we write GW_LAN (connected to DHCP Server) RTR_LAN (connected to client) ip add (of the first relay agent) ?

Please someone help me to clear this confusion!
