Route publishing method and device, and network equipment

The invention provides a route publishing method and device, and network equipment, wherein the method comprises the steps that when network equipment of a core layer receives a route published by network equipment of other autonomous systems, through a matching route strategy, the routing information meeting the condition is not released to the access equipment in the autonomous domain where the network equipment of the core layer is located any more, so that routing learning between two isolated autonomous systems can be inhibited, the consumption of routing table entries of the access equipment is reduced, and the number of users online through the boundary equipment can be increased. 本说明书提供一种路由发布方法及装置、网络设备，所述方法包括：核心层的网络设备接收到其他自治系统的网络设备发布的路由时，通过匹配路由策略，针对符合条件的路由信息不再向该核心层的网络设备所在的自治域中的接入设备发布，从而可以抑制两个隔离的自治系统间的路由学习，减少了接入设备的路由表项的消耗，从而可以增大通过该边界设备上线的用户数量。
