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.

摘要： A provider edge (PE) device and a method implemented thereon are disclosed for Ethernet virtual private network (EVPN). According to an embodiment, a first PE device performs label assignment procedure with a second PE device such that the first and second PE devices share an Ethernet segment identifier (ESI)-excluded label and know a correspondence between the ESI-excluded label and a label combination of an ESI label and a VPN label. The first PE device encapsulates a packet of broadcast, unknown unicast or multicast (BUM) traffic, with the ESI-excluded label instead of the label combination. The first PE device sends the encapsulated packet to the second PE device.
