[LEFT]Router#erase startup config
Reload[/LEFT]

ممنون از راهنماييتون ولي نشد

ببین دوست من این موارد تو بخشها مربوط بهش توضیح داده شده ولی مختصر میگم:
[LIST=1][*]Check the configuration register on the router by issuing the [B]show version[/B] command.
The configuration register setting is displayed in the last line of the [B]show version[/B] command output and should be set to 0x2102. If this is not the case, enter the [B]config-register 0x2102[/B] command once in global configuration mode.
[INDENT]router#[B]configure terminal[/B]router(config)#[B]config-register 0x2102[/B]router(config)#[B]end[/B]router#[/INDENT]If the [B]show version[/B] command is issued again, the same line in the command output will have '[B](will be 0x2102 at next reload)[/B]' appended to the current register setting.[*]Erase the current start-up configuration on the router with the [B]write erase[/B] command.[*]Reload the router with the [B]reload[/B] command. When prompted to save the configuration, [B]DO NOT[/B] save.
[INDENT]router#[B]reload[/B]System configuration has been modified. Save? [yes/no]: [B]n[/B]Proceed with reload? [confirm][/INDENT]Once the router reloads, the System Configuration Dialog appears.
[INDENT] --- System Configuration Dialog ---Would you like to enter the initial configuration dialog? [yes/no]:[/INDENT]The router is now reset to the original factory defaults. [/LIST][B]Method 2 [/B]

This method uses the [B]config-register 0x2142[/B] command in global configuration mode.
[LIST=1][*]Enter the [B]config-register 0x2142[/B] command in global configuration mode.
[INDENT]router(config)#[B]config-register 0x2142[/B][/INDENT]This causes the router to ignore the start-up configuration on the next reload. If a [B]show version[/B] is issued, the last line in the command output will have '[B](will be 0x2142 at next reload)[/B]' appended to the current configuration register setting.[*]Reload the router using the [B]reload[/B] command in enable mode. It is not necessary to save when prompted to save the system configuration.
[INDENT]router#[B]reload[/B]System configuration has been modified. Save? [yes/no]: [B]n[/B]Proceed with reload? [confirm][/INDENT]After the router has reloaded, the System Configuration Dialog appears. [*]Enter [B]no[/B] to the question "Would you like to enter initial configuration dialog?"[*]Change the configuration register setting to 0x2102 by entering the [B]config-register 0x2102[/B] command once in global configuration mode.[*]Issue the [B]write memory[/B] command in enable mode to overwrite the existing start-up configuration with the current running configuration. [*]Reload the router with the [B]reload[/B] command in enable mode.
Once the router reloads, the System configuration Dialog appears.
[INDENT] --- System Configuration Dialog ---Would you like to enter the initial configuration dialog? [yes/no]:[/INDENT]The router is now reset to the original factory defaults.[/LIST]

راستش باز متوجه نشدم

فایل startup-config رو با دستور Delete پاک کن

ببخشيد مسير دستور delete كجاست
راستي من با برنامه NetSim شبيه سازي كردم و روتري رو هم كه دارم روش كار ميكنم 1710 مي باشد
ممكنه IOS اين مدل اين دستور رو پشتيباني نكنه
بازم تشكر ميكنم

write erase رو بزن فکر کنم مشکلت حل بشه.

یه نگاهی هم به این بنداز دقیقا توضیح داده.
