Hello

Hey !! does Fallback sequence in a router i.e. of FLASH , TFTP , ROM IOS happens by deafult or we manually need to configure it using boot system command

Hi,

this is the configuration register that determines the default sequence.

Hi arpit,

it is done by default. You can change it but there no real reason or scenario where you want to do that. Should you desire one day to start a router from a TFTP/PXE you will find particular procedures for each platform (quite similar actually ) and as Alain was telling you need to change register settings
