DHCP options

Hello

How can i configure the filename on an dhcp server what filename the router should look at the tftp server?

The dhcp option 66 only sends the ip of the tftp sever

so the router looks at 

%Error opening tftp://192.168.1.30/router-confg (No such file or directory)
%Error opening tftp://192.168.1.30/ciscortr.cfg (No such file or directory)
%Error opening tftp://192.168.1.30/network-confg (No such file or directory)
%Error opening tftp://192.168.1.30/cisconet.cfg (No such file or directory)
%Error opening tftp://192.168.1.30/router-confg (No such file or directory)
%Error opening tftp://192.168.1.30/ciscortr.cfg (No such file or directory)
%Error opening tftp://192.168.1.30/network-confg (No such file or directory)
%Error opening tftp://192.168.1.30/cisconet.cfg (No such file or directory)

but i would fix this to a filename i created

Hello @Raimund Schimanovits,

Use boot system command followed by the filename you want to request from the TFTP server. 

boot system tftp://192.168.1.30/your-filename

192.168.1.30 - is this your TFTP Server , then you should have configuration in the route folder for the router to pickup and config and load.
