Abstract:
1. A method comprising: accessing a configuration file with a control node of a multi-chassis router having a plurality of chassis, the configuration file including configuration data for a configuration update of the multi-chassis router; pruning the configuration file by removing configuration data not relevant to the operation of one or more of the plurality of chassis to form one or more pruned configuration files each including less configuration data than the configuration file, wherein pruning the configuration file comprises: sending the one or more pruned configuration files from the control node to the plurality of chassis; receiving, with the control node, validation results from the plurality of chassis for the one or more pruned configuration files sent from the control node to the plurality of chassis; when a successful validation result is received from each chassis of the plurality of chassis, committing the control node to the configuration data in the configuration file and sending a commit command from the control node to each of the plurality of chassis to commit the plurality of chassis to the one or more pruned configuration files.
