Under which two circumstances would a router usually be configured as a DHCPv4 client?
A router would usually be configured as a DHCPv4 client under the following two circumstances:
1. Home Network Setup: In a typical home network setup, the router acts as the central point for connecting different devices to the internet. In this scenario, the Internet Service Provider (ISP) assigns a dynamic IP address to the router through DHCP. The router acts as a DHCPv4 client to obtain this IP address dynamically from the ISP’s DHCP server. This allows the router to obtain a valid IP address, subnet mask, default gateway, and other necessary network configuration parameters from the DHCP server.
2. Remote Office/Branch Office (ROBO) Networking: In a remote office or branch office setup, where multiple offices are connected through a Wide Area Network (WAN), each office may have its own local router. In this case, the main office or data center usually assigns IP addresses dynamically to the remote office routers via DHCP. Each remote office router acts as a DHCPv4 client to obtain a valid IP address for its WAN interface. This allows the routers to establish connectivity and communicate with the main office or other remote offices over the WAN.
In both of these situations, configuring the router as a DHCPv4 client simplifies the network setup process by automating the assignment of IP addresses and other network parameters. It eliminates the need for manual configuration of IP addresses on each router, making it easier to manage and maintain the network.
