Title: TWO-LAYER NETWORK, AND LOOPBACK DETECTION METHOD OF TWO-LAYER NETWORK
Abstract:
The embodiments of the invention provide a two-layer network, and a loopback detection method of a two-layer network. The method comprises: upon a network node in a two-layer network configuring a MIP to detect a BIER forwarding table or a MAC forwarding table, transmitting, to remaining network nodes, an MIP address for detecting the BIER forwarding table or the MAC forwarding table; upon activation of a loopback detection function from an MEP to a target MIP, transmitting, by the MEP, a loopback detection packet carrying a target MIP address; and upon one network node in the two-layer network receiving the loopback packet, when no MIP is configured at the network node, or a configured MIP address is inconsistent with the target MIP address, forwarding, according to the target MIP address, and based on the BIER forwarding table or the MAC forwarding table, the loopback detection packet.
