1. A method, comprising:
maintaining, by a provider edge device associated with a link aggregation group (LAG) and according to a link aggregation control protocol (LACP), a set of links that connect the provider edge device to a consumer edge device associated with the LAG;
determining, by the provider edge device, that the provider edge device is not receiving link aggregation control protocol data units (LACPDUs) from the consumer edge device via the set of links;
receiving, by the provider edge device, a message from another provider edge device associated with the LAG;
processing the message to determine that the other provider edge device is not receiving LACPDUs from the consumer edge device;
causing, by the provider edge device, and based on determining that the provider edge device is not receiving LACPDUs from the consumer edge device and determining that the other provider edge device is not receiving LACPDUs from the consumer edge device, the set of links to have a maintain LAG status,
wherein causing the set of links to have the maintain LAG status causes the provider edge device to keep up the set of links and to cease maintaining the set of links according to the LACP; and
routing, by the provider edge device and based on causing the set of links to have the maintain LAG status, one or more packets to or from the consumer edge device via the set of links.
