Overview
The DHCP server is well suited to networks where:
Manual configuration and centralized management are difficult to implement.
IP addresses are limited. For example, an ISP limits the number of concurrent online users, and users must acquire IP addresses dynamically.
Most hosts do not need fixed IP addresses.
An MCE acting as the DHCP server can assign IP addresses not only to clients on public networks, but also to clients on private networks. The IP address ranges of public and private networks or those of private networks on the DHCP server cannot overlap. For more information about MCE, see MPLS Configuration Guide.
