FAST RECEIVE RE-CONVERGENCE OF MULTI-POD MULTI-DESTINATION TRAFFIC IN RESPONSE TO LOCAL DISRUPTIONS

摘要

One technique includes receiving, in a first network, a multi-destination packet from a second network, and determining, based on the multi-destination packet, a first multi-destination tree in the first network for forwarding the multi-destination packet. In response to determining that the first multi-destination tree is not rooted on the network device, a second multi-destination tree in the first network is determined, and the multi-destination packet is transmitted using the second multi-destination tree. Another technique includes, upon detecting a first network device joining a network, sending a first indication to a second network device that the first network device is in a state for an amount of time. After the amount of time has elapsed, a second indication that the first network device has exited the state is sent to the second network device. A topology of the network is updated after the first network device has exited the state.
