摘要
A method of avoiding routing interruption during transition to a topology transparent zone (TTZ) is described. The method includes 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.
