摘要:
A method by a network device functioning as a provider edge (PE) in an ethernet virtual private network (EVPN) to prevent transient loops between multi-home peer PEs. The method includes advertising a first EVPN label to one or more PEs that are multi-home peer PEs of the PE, advertising a second EVPN label to one or more PEs that are not multi-home peer PEs of the PE, receiving first traffic for a CE that is encapsulated with the first EVPN label as opposed to the second EVPN label, and discarding the first traffic in response to determining that a link between the PE and the CE is not operational and the first traffic for the CE is encapsulated with the first EVPN label.
