Therefore, without additional configuration, DHCP servers are only assigned to assign IP addresses to clients on your local network.
Routers do not normally broadcast unless they are configured to allow. We know that DHCP clients use broadcasts to obtain an IP address from the DHCP server. Therefore, “RFC 1542 Compliant Router” is a router that supports the transmission of DHCP broadcast traffic. Relay agents are part of the DHCP standards and operate according to standard documents (RFCs) that define protocol design and related behavior. The DHCP Relay Agent is, therefore, a server or router configured to listen for DHCP broadcasts from DHCP clients and forward these messages to DHCP servers on different subnets. There are very few computers and it is not worth putting a dedicated server to specify their addresses, so there are two options putting a fixed IP address on these computers, or configuring a DHCP relay agent service. In other words, since finding a DHCP server to obtain an address is a very important service, there is an exception to allow these large mass traffic to find a DHCP server and to find these computers from other offices. There is a way to ensure that these DHCP requests for broadcast traffic on the routers run. One office is located in the Center and the other is located in the Branch office in a nearby or remote location. Now, suppose there are two small networks. How to Enable DHCP Relay Agent on Cisco Router Since this traffic does not pass through routers, it cannot obtain an address if it cannot find a DHCP in the same segment.
However, a computer searches for DHCP by broadcasting over the network segment for an IP address request. We know that broadcast traffic doesn’t pass through routers.
