DHCP发现(DISCOVER) client在物理子网上发送广播来寻找可用的服务器。网络管理员可以配置一个本地路由来转发DHCP包给另一个子网上的DHCP服务器。该client实现生成一个目的地址为255.255.255.255或者一个子网广播地址的UDP包。 客户也可以申请它使用的最后一个IP地址(在下面的例子里为192.168.1.100)。如果该客户所在的网...

that 99 % of the former “work” for this router (on former OpenWRT release) still works very well now after the migration. Furthermore I want to add, that I do clean installations only, when upgrading to a new software release.

If you use the Cisco IOS DHCP server on the router, you can enter thedebug dhcp detailcommand and thedebug ip dhcp server eventscommand in order to view the DHCP client and server activity. Here is an example from thedebug ip dhcp server eventscommand: ...
DHCP server can also assign IP addresses to non-directly connected network segments. As shown in Fig. 11.7, AR1 is configured as a DHCP server to assign IP addresses to the R&D department. This requires enabling DHCP relay on interface Vlanif 1 of router AR2....
Verify whether your clients can receive their IP config via DHCP. If yes then there is nothing more to tweak. Otherwise, proceed further. If you are running a DHCP server on an IOS-based device (router, switch), you may need to use the command ip dhcp relay information trust-all (...
