Abstract
A technique for operating a network involves controlling the black-holing of traffic by selectively redirecting unicast traffic destined for a dual-homed customer equipment (CE) device from a first provider backbone bridge (PBB) provider edge (PE) device to a second PBB PE device in response to a service failure. Unicast traffic is selectively redirected from the first PBB PE device to the second PBB PE device for a time interval that is long enough to enable the customer source MAC address (CMAC)-to-backbone MAC address (BMAC) association of the second PBB PE device to be learned by other PBB PE devices.
