Abstract:
1. A method comprising: establishing, by a network device, an active pseudo-wire and a standby pseudo-wire, with respect to another network device, based on a virtual private local area network service (VPLS) advertisement transmitted between the network device and the other network device; detecting, by the network device, a communication link failure associated with a customer device, of a plurality of customer devices associated with the active pseudo-wire and the standby pseudo-wire; determining, based on detecting the communication link failure and for each customer device, of the plurality of customer devices, whether an identification value, associated with the customer device, corresponds to the active pseudo-wire; and determining, for each customer device, of the plurality of customer devices, not to utilize the standby pseudo-wire when the identification value does not correspond to the active pseudo-wire, where the network device utilizes the standby pseudo-wire, rather than the active pseudo-wire, when the identification value corresponds to the active pseudo-wire.
