I'm using Dynamips for my ccna lab, but I always get an error message on RouterB. Anyone knows the reason, and how to turn it off? Thanks in advance.

This error message is related to the default service configuration option built into Cisco IOS software, which attempts to access the service configuration files from a network Trivial File Transfer Protocol (TFTP) server.

In order to disable this feature, issue the no service config global command.
Router#config terminal
Enter configuration commands, one per line.
Router(config)#no service config
Router(config)#exit
Router#copy running-config startup-config

This error message will no longer appear at the next reboot of the router.
