Creating DHCP Relay Servers

DHCP provides a mechanism through which computers using TCP/IP can obtain protocol configuration parameters automatically from a DHCP server on the network.

The DHCP server is typically centrally located and operated by the network administrator. An IP client contacts a DHCP server for configuration parameters. Because the server is run by a network administrator, DHCP clients can be reliably and dynamically configured with parameters appropriate to the current network architecture.

For PPP users, the E-series device acts as a DHCP client to obtain an address for the PPP user. This is referred to as DHCP proxy.

DHCP proxy client support enables the device to obtain an IP address from a DHCP server for a remote PPP client. Each virtual router (acting as a DHCP proxy client) can query up to five DHCP servers.

To create a DHCP relay server:

1. From the Configuration menu, select Create, and click DHCP Relay Server. The Create DHCP Relay Server dialog box appears.
2. Set the DHCP relay server parameters (Table 47).

Setting the parameters allows you to identify a DHCP server as a network resource. When you associate a server with a virtual router, you can set parameters that can be specific to that particular virtual router. See Chapter 3, Configuring Virtual Routers.
