AutoInstall via tftp - faling to select tftp server.

[Niklas.D]

Hi! 

So i am trying to get the AutoInstall to work on a router. 

I  configed it to use DHCP 

interface GigabitEthernet0
ip address dhcp
duplex auto
speed auto

I can monitor the DHCP and see that it gets the  DHCP: Scan: TFTP Server address Option: 

With my tftp server.

But still the router is trying to use 255.255.255.255 ! 

Apr 19 11:13:03.700: DHCP: Client socket is closed
%Error opening tftp:/ /255.255.255.255/ir800-confg (Timed out)
*Apr 19 11:13:30.712: %SYS-4-CONFIG_RESOLVE_FAILURE: System config parse from (tftp:/ / 255.255.255.255/ir800-confg) failed

*Apr 19 11:14:08.724: %SYS-4-CONFIG_RESOLVE_FAILURE: System config parse from (tftp://255.255.255.255/ir800.cfg) failed

 - Does it get an ip address from the DHCP server ? . Check the logs of your DHCP-service for that ?

 - So it broadcasts or queries any tftp server available for ir800-confg or ir800.cfg  ,  when looking at , the first filename is peculiar but could be possible. Is any of such files provisioned on an online tftp service in the subnet ? Look at the logs of your tftp server, check if it actually being addressed by the router. (or not).
