摘要： A method of avoiding routing interruption during transition to a topology transparent zone (TTZ) including virtualizing a path from an edge router to another edge router within the TTZ in a first direction without removing original links, wherein the original links are links from the edge router to its neighboring routers within the TTZ, receiving, by the edge router within the TTZ, a router link state advertisement (LSA) from the another edge router within the TTZ while the original links remain in place, wherein the LSA comprises a path from the another edge router to the edge router in a second direction different from the first direction, and removing, by the edge router within the TTZ, the original links after the LSA has been received from the another edge router and the virtualization of the path is complete.

摘要翻译：一种在转换到拓扑透明区域（TTZ）期间避免路由中断的方法，包括在不消除原始链路的情况下虚拟化从TTG内的边缘路由器到另一边缘路由器的路径，其中原始链路是来自边缘路由器的链路到TTZ内的相邻路由器，由TTZ内的边缘路由器接收来自TTZ内的另一个边缘路由器的路由器链路状态通告（LSA），同时原始链路保持原位，其中LSA包括从在与第一方向不同的第二方向上的边缘路由器的另一边缘路由器，并且在从另一边缘路由器接收到LSA之后，由TTZ内的边缘路由器去除原始链路，并且路径的虚拟化完成。
