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.

摘要： In one embodiment, a computer networking device calculates a first hash value for an identifier of a group of computing devices, as well as a second hash value for the identifier of the group of computing devices, with each hash value being at least in part on the identifier of the group of computing devices and an identifier of the respective interface. The computer networking device may also analyze the first hash value with respect to the second hash value and select the first interface for association with the identifier of the group of computing devices based at in part on the analyzing. The computer networking device may further store an indication that the identifier of the group of computing devices is associated with the first interface.
