Efficient split management in an MC-LAG

A non-transitory computer-readable storage medium storing instructions to:

• receive, by a first network device, control information associated with a control protocol running on a multi-chassis link aggregation group (MC-LAG) from a first link coupling a second network device of the MC-LAG;
• determine, by the first network device, whether the second network device is operational via a second link coupling the second network device, wherein the second link is separate from the first link;
• determine that a split has occurred in the MC-LAG in response to determining unavailability of the first link and availability of the second network device via the second link;
• subsequent to determining the split, check a set of selection conditions in a predetermined order based on a first set of operational information associated with the first network device and a second set of operational information associated with the second network device;
• and
• select the second network device for forwarding traffic of the MC-LAG in response to the set of selection conditions indicating the second network device is to be selected.

A computer system, comprising:

• one or more processing resources;
• and
• a non-transitory computer-readable storage medium storing instructions that when executed by the one or more processing resources cause the computer system to:
• receive control information associated with a control protocol running on a multi-chassis link aggregation group (MC-LAG) from a first link coupling a second computer system of the MC-LAG;
• determine whether the second computer system is operational via a second link coupling the second computer system, wherein the second link is separate from the first link;
• determine determining that a split has occurred in the MC-LAG in response to determining unavailability of the first link and availability of the second computer system via the second link;
• subsequent to determining the split, check a set of selection conditions in a predetermined order based on a first set of operational information associated with the computer system and a second set of operational information associated with the second computer system;
• and
• select the second computer system for forwarding traffic of the MC-LAG in response to the set of selection conditions indicating the second computer system is to be selected.
