Administration of the Avaya G350 Media Gateway - Avaya Support

Configuring DHCP and BOOTP relayConfiguring DHCP and BOOTP relayYou can configure the router to relay Dynamic Host Configuration Protocol (DHCP) andBOOTstrap Protocol (BOOTP) client broadcasts to a server on a different segment of thenetwork. When you configure DHCP and BOOTP relay, you can control how the router relaysDHCP and BOOTP packets. The router also relays replies from the server back to the client.The G350 can alternatively function as a DHCP server, providing DHCP service to localdevices. For information about configuring DHCP server on the G350, see Configuring DHCPserver on page 179.DHCPDHCP assigns dynamic IP addresses to devices on a network. With dynamic addressing, adevice can have a different IP address whenever the device connects to the network. In somesystems, the device’s IP address can even change while it is still connected. DHCP alsosupports a mix of static and dynamic IP addresses.Dynamic addressing simplifies network administration because the software keeps track of IPaddresses rather than requiring an administrator to manage the task. This means you can add anew computer to a network without needing to manually assign a unique IP address. Many ISPsuse dynamic IP addressing for dial-up users. However, dynamic addressing may not bedesirable for a network server.BOOTPBOOTP is an Internet protocol that allows a diskless workstation to discover the following:●●●Its own IP addressThe IP address of a BOOTP server on the networkA file to be loaded into memory to boot the workstationBOOTP allows the workstation to boot without requiring a hard disk or diskette drive. It is usedwhen the user or station location changes frequently. The protocol is defined by RFC 951.Issue 3 January 2005 177
