Detection method for learning capability of EVPLAN address under marking mode

Abstract

The invention relates to a method for detecting address learning ability of markedness model EVPLAN , which comprises the following steps: collocating three PE nodes and establishing the markedness model EVPLAN made of the three PE nodes; setting different MAC address for ports of corresponding client equipment or an analyzer (4) and establishing physical connection with the PE nodes; the analyzer sends to a first port Ethernet frames which contain VLAN marks and the target address of MAC is a second port and then records corresponding receiving situations of the second and third ports; whether the markedness model EVPLAN has corresponding address learning ability is judged according to the address learning ability requirements and the receiving situations sent for the first and the second or more times at the previous step. The method can effectively verify whether the markedness model EVPLAN established in MSTP environment has address learning ability.

Description

technical field [0001] The invention relates to communication, network and test technology, in particular to a method for detecting the address learning capability of a Tagged Mode Ethernet virtual private network EVPLAN created in a multi-service transmission node MSTP network environment. Background technique [0002] The Communication Industry Standard of the People's Republic of China "Technical Requirements for SDH-Based Multi-Service Transport Node (MSTP) - Embedded MPLS Function Part" refers to "operator's edge equipment PE node", "operator's core equipment P node", and "flow classification" , "Multi-Protocol Label Switching MPLS Layer Processing" and "Layer 2 Virtual Private Network L2VPN Reference Model" put forward relevant requirements. The PE node, P node, flow classification, MPLS layer processing and L2VPN reference model in this application document conform to this standard. [0003] The multi-service transport node MSTP with embedded MPLS function based on S...

Problems solved by technology

[0009] In the MSTP network environment, using the customer VLAN tag as the delimiter of the EVPLAN service not only maintains the original characteristics of the local service, but also can realize refined service management, but there is currently no effective test for the address learning ability of the tagged mode EVPLAN method, hindering the popularization and application of this type of EVPLAN business
