We have been using a dhcp and tftp server to automatically configure branch WAN routers such as 1751's and 1841's for years but, have recently purchased a 1921 and 1941 as possible next generation replacements.
The problem is when the 1900 series power up instead of getting a dhcp address directions to the tftp server it boots up and asks for the user name to be immediately changed or you will be "locked out". Does anybody know a workaround to this so that I can again go back to download my common configuration? Does anybody have any other way of automatically configuring the newer version ios? Doing extra steps for 500 WAN branch routers is time consuming. Doing configurations without automation for that many is moving in the wrong direction.
Stuck in the past with ver 12.x.
