摘要： An apparatus configured to provide active-active access to a transparent interconnection of lots of links (TRILL) campus. The apparatus includes a first access port associated with a first customer equipment (CE) and a second access port associated with a second CE. The first access port is configured to receive a frame from the first CE. The apparatus includes a processor configured to replicate the frame to generate a replicated frame, determine that a pseudo-nickname associated with the first access port and the pseudo-nickname associated with the second access port are the same, and determine that the first access port and the second access port are associated with different multi-chassis link aggregations (MC-LAGs). The apparatus also includes a transmitter configured to forward the replicated frame to the second CE using the second access port.

摘要： A method implemented by a network component is provided. The method includes receiving a Virtual Station Interface (VSI) Discovery Protocol (VDP) request from an Edge Virtual Bridging (EVB) station and transmitting, to the EVB station, a VDP Response in response to the request. The VDP Response includes a VDP Type-Length-Value (TLV) having a Filter Information field. The Filter Information field is configured to specify a Priority Code Point (PCP) value associated with one or more Virtual Local Area Network (VLAN) Identifier (VID) values carried by the VDP Response. The PCP value is carried in a PCP field and adopted by the EVB station as a default PCP value associated with the VSI and at least one VID. The Filter Information field further contains a PCP Significant (PS) field associated with each PCP field, and wherein the PS field indicates whether the PCP field carries the PCP value.
