With DHCP external server, all communication between the subscriber and the DHCP server is monitored by the E-series router. The subscriber requests an address from the DHCP server through the E-series router. After the subscriber receives an IP address, the subscriber can access the Internet and use the value-added services provided by the E-series router and by the SRC software. The edge network must be using a DHCP relay function.
The services provided by integrating the E-series router’s DHCP external server application with SRC software are similar to those provided when the DHCP local server is integrated with SRC software. For more information, see SRC-PE Getting Started Guide, Chapter 1, SRC Product Overview.
