A configuration is identified as a rescue configuration. The identified rescue configuration is stored in a storage device (if it is not already stored). The stored rescue configuration may then be used to configure an apparatus, such as a router, in response to a rescue command. Identifying a particular configuration as a rescue configuration can be done by a manual command. The identifying may be limited such that it is effected only if performed by an authorized user. Alternatively, the identification of a configuration as the rescue configuration can be done automatically. For example, an automatic rollback to a known functioning configuration can occur automatically (e.g., in response to a rescue command). A configuration may be determined to be the known functioning configuration using various factors.
