I've been tasked with updating our DHCP boxes and have to change out the ip helper address on hundreds of routers (multiple different subinterfaces/subnets). Besides for downloading existing configs, changing them, and then re-uploading...... Does anyone know of a efficient way to script this process, or point me in the correct direction for this? It doesn't look like there is a lot on the internet/forums about scripting this, or going about this in an efficient manner. Thanks for any advice on this.
All routers will be cisco devices, but numerous different models.
