 Symptom: In the version after F2604, the password encryption within configuration files has been
enhanced and cannot be interpreted by earlier revisions of the agent code. This means that if a unit
is downgraded to earlier code, it may no longer be possible to login and manage the device.
 Condition: Upgrade the code from the version before F2604 to F2064 or later version.
 Workaround:
 Before upgrading to the new code, it is necessary to ensure password control is disabled.
Execute the “undo password-control enable” and then save this configuration file as a backup
in case you need to downgrade the software again. If it is later necessary to downgrade to
earlier software, force the router to use this backup configuration file by executing a ”startup
saved-configuration (filename)” command before rebooting to the old code. Then, after the
code has been downgraded, the device can be logged in from the console or by Telnet, but not
SSH. The SSH authentication details will need to be reset.
 If no backup configuration has been saved but it is still possible to access the device
management via some method while running the old code (e.g. Console, Telnet or SSH), then
you can redefine all the device management passwords as required.
 If after a downgrade it is impossible to login to the device via any method, then there are two
ways to recover the router:
 From the BOOT menu, set the new code to run again and reboot the device. Disable Telnet
authentication:
User-interface vty 0 4
Authentication mode none
Then save the configuration and downgrade the code again, login via Telnet and reset all
the passwords as required.
 From the BOOT menu. On boot-up, use Ctrl+B to enter the Boot menu and then force the
unit to use the factory default configuration (bypassing the user configuration). The unit will
then need to be fully reconfigured.

 The more specific route has a vt egress interface, and another route has a tunnel egress
interface.
 Traffic that should be forwarded through the vt interface is forwarded through the tunnel
interface.
 Workaround: None.

route has been changed or deleted, protocol is OSPF", which should be output by the active MPU.
