Rollback-on-error support for forwarding components of a network device

A network device, comprising:

• one or more memories;
• and
• one or more processors, coupled to the one or more memories, to:
• receive an original configuration that includes configuration objects;
• generate, based on the original configuration, a dependency graph that includes nodes and entries representing the configuration objects,
• wherein the dependency graph is a representation of a packet topology;
• receive a configuration update that includes one or more new configuration objects;
• update the dependency graph based on the configuration update and to generate an updated dependency graph that includes one or more new nodes and one or more new entries representing the one or more new configuration objects;
• test the configuration update, based on the updated dependency graph, to determine whether the configuration update fails or succeeds;
• and
• selectively:
• implement the configuration update based on the configuration update succeeding, or
• perform a rollback of the configuration update, based on the updated dependency graph and based on the configuration update failing, to restore the original configuration.

A non-transitory computer-readable medium storing a set of instructions, the set of instructions comprising:

• one or more instructions that, when executed by one or more processors of a network device, cause the network device to:
• receive an original configuration that includes configuration objects;
• generate, based on the original configuration, a dependency graph that includes nodes representing and entries representing the configuration objects;
• receive a configuration update that includes one or more new configuration objects,
• wherein the original configuration and the configuration update are associated with a packet forwarding component of the network device;
• update the dependency graph based on the configuration update and to generate an updated dependency graph that includes one or more new nodes or one or more new entries representing the one or more new configuration objects;
• test the configuration update, based on the updated dependency graph, to determine whether the configuration update fails or succeeds;
• and
• selectively:
• implement the configuration update based on the configuration update succeeding, or
• perform a rollback of the configuration update, based on the updated dependency graph and based on the configuration update failing, to restore the original configuration.
