请教下
启动机器主板请求dhcp正常拿到了启动文件,加载启动文件后,又去请求dhcp(临时文件系统内发的请求),然后碰到
碰到no dhcpoffers received. no working leases in persistent database,
image

baremetal agent上tcpdump抓包看到发出的offer到了网关上,没有继续转发;it 的同事没发现什么线索,
请问为什么第二次dhcp会失败呢?有没有办法让第二次使用第一次获取到的IP呢?
谢谢。

@vincentiss 理论上如果能 pxe 启动成功,第二次 dhcp 也是走的同样路径。如果 agent 做了 dhcp response,应该还是网络原因,需要确保整个二层网络环境中没有其他的 dhcp 服务。
