Embodiment Construction
[0031] The method for defect perception and routing entry refreshing of the three-layer Ethernet ring provided by the present invention will be described in detail below in conjunction with the accompanying drawings.
[0032] Such as figure 1 As shown, the three-layer Ethernet ring defect perception method provided by the present invention comprises the following steps:
[0033] Step A10, forming a topological address list with the node address information of each node on the ring topology in the order of sending from east to west, setting an eastbound access interface on the east of each node of the ring topology, and setting a westbound access interface on the west; Bind the eastbound access interface and the westbound access interface as a ring access interface pair, and set corresponding address information for it.
[0034] Such as figure 2 As shown, the address list of node A is: A(1.1.1.1 / 32)-B-C-D-E-F-A; the eastbound access interface is A1, the westbound access inte...
