Example 31 with DHCP

use of org.onlab.packet.DHCP in project dhcpl2relay by opencord.

the class DhcpL2RelayTestBase method constructDhcpNakPacket.

/**
 * Constructs DHCP Nak Packet.
 *
 * @return Ethernet packet
 */

    UDP udpPacket = (UDP) ipv4Packet.getPayload();
    DHCP dhcpPacket = (DHCP) udpPacket.getPayload();
    dhcpPacket.setOptions(constructDhcpOptions(DHCP.MsgType.DHCPNAK));
