[c-nsp] IOS Initial setup function & DHCP

[Tony]

I don't have any personal experience, this is just reading the doco. This guide references "autoinstall" in section 6 "configure the router":

http://www.cisco.com/en/US/docs/routers/7200/install_and_upgrade/7201_quick_start/11363q.html

This next doc gives more info on the "autoinstall" process:

http://www.cisco.com/en/US/docs/ios/fundamentals/configuration/guide/cf_config_overview_ps6350_TSD_Products_Configuration_Guide_Chapter.html

including the pre-requisite: "A DHCP server is available on the network to provide IP addresses to networking devices that are using AutoInstall over a LAN connection."


Given the above, I'd say it's highly likely that your shiny new 7201 did issue a DHCP request when it was booted up :(

regards,
Tony.
