agent is any host that forwards DHCP packets between clients and servers. Relay
agents are used to forward requests and replies between clients and servers when
theyarenotonthesamephysicalsubnet.Relayagentforwardingisdistinctfromthe
normal forwarding of an IP router, where
 IP datagram are switched between net‐
