Abstract
A multi-chassis router allows an administrator to install software from a single user interface. The multi-chassis router automatically forwards the software to each chassis within the multi-chassis router when given a single command to install the software from an administrator. The multi-chassis router also automatically validates the software on each chassis. After reporting the results of the validations, the multi-chassis router may wait for the administrator to issue a commit command before committing each chassis within the multi-chassis router to the software. Alternatively, in response to a failed validation or for other reason, an administrator can issue a single ROLLBACK command. This allows each chassis within the multi-chassis router to have the same software during all stages of a software installation and ensures software on each chassis is compatible with software on every other chassis.
