Abstract

The embodiment of the present invention provides a layer 2 network and a loopback detection method of the layer 2 network, the method comprising: after any network node in the layer 2 network is configured to detect the MIP of the BIER forwarding table or the MAC forwarding table, Send the MIP address used to detect the BIER forwarding table or MAC forwarding table to other network nodes; after starting the loopback detection function from the MEP to the target MIP, the MEP sends a loopback detection message carrying the target MIP address; After receiving the loopback detection message, any network node in the local network node does not configure MIP, or the address of the configured MIP is inconsistent with the target MIP address, the loopback detection message is forwarded based on BIER according to the target MIP address. Published forwarding or forwarding based on MAC forwarding tables.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a layer 2 network and a loopback detection method for the layer 2 network, which is applicable to the scene where Bit Indexed Explicit Replication (BIER) is applied to the layer 2 network, where The Layer 2 network is a data link layer network. Background technique [0002] In the current Ethernet, the standard organization Institute of Electrical and Electronics Engineers (IEEE for short) has formulated a working mechanism of Ethernet operation, administration and maintenance (OAM for short), and It was officially released as the 802.1ag standard in 2007. [0003] The IEEE 802.1ag standard defines the logical entity of the OAM function in the Ethernet, which includes the Maintenance End Point (MEP) located at both ends of the Ethernet transmission path, and the Maintenance Intermediate Point (Maintenance Intermediate Point) located in the middle of the Ethernet t...
