If you ever find yourself locked out of router, you’ll want to do this next time:
Note: A common pitfall when configuring access lists on remote routers is to inadvertently “lock yourself” out. This is not a big problem when the router is physically located local. However, this could be a huge problem if the router is physically located in another geographical location.
For this reason, it is strongly suggest that the reload in 30 command be issued on the remote router. This would automatically reload the remote router within 30 minutes of issuing the command. Therefore, if the administrator was locked out, it would eventually reload to the previous configuration, allowing access to the router again. Use the reload cancel command to deactivate the pending reload.
