Figure 1-30. Boot Error Messages
The error messages in Figure 1-30 were displayed during bootup. In this
particular case, the startup-config file has VPNs configured, and the router
that is booting does not have the IPSec VPN module that enables these
commands. The VPN commands are reported as errors.
You can use error messages like these to locate and troubleshoot a problem
in the router's configuration.
