Configuring SSO<br />
Following the reload, each RP is in its default mode:<br />
• The <strong>Cisco</strong> 7304 series router reboots in SSO mode.<br />
• The <strong>Cisco</strong> 7500 series router reboots in HSA mode.<br />
• The <strong>Cisco</strong> 10000 series Internet router reboots in SSO mode.<br />
• The <strong>Cisco</strong> 12000 series Internet router reboots in RPR mode.<br />
<strong>Stateful</strong> <strong>Switchover</strong><br />
Configuration Tasks<br />
Specifies the filename of an image stored in Flash<br />
memory or on a TFTP server.<br />
The <strong>Cisco</strong> 10000 series Internet router is the only<br />
networking device capable of being configured to<br />
boot from a TFTP server.<br />
Modifies the existing configuration register setting<br />
to reflect the way in which you want to load a<br />
system image.<br />
• value—0x0 to 0xFFFF<br />
Exits configuration mode and returns the router to<br />
privileged EXEC mode.<br />
Saves the configuration changes to the startup<br />
configuration file.<br />
Reboots both RPs on the device to ensure that<br />
changes to the configuration take effect.<br />
Note <strong>Cisco</strong> 7304 routers and <strong>Cisco</strong> 10000 series Internet routers operate in SSO mode by default after<br />
reloading the same version of SSO-aware images on the device. No configuration is necessary.<br />
