Method for transmitting packet in resilient packet intersect ring includes: at least two resilient packet intersect ring intersect each other on two intersect node, the intersect node receives a broadcast packet from the first resilient packet ring, and copies the said broadcast packet; the said intersect node judges whether allowing to insert the said broadcast packet into the second resilient packet ring by spanning the ring according to the identification information included in the said copied broadcast packet, if so, inserting into the second resilient packet ring by spanning the ring and broadcasting, otherwise, discarding the said broadcast packet, the control condition of allowing to broadcast by spanning the ring of all intersect nodes is null. The invention can ensure that when all intersect nodes can transmit spanning ring server, it avoids spanning ring broadcast storm. The invention is applied to the case that several resilient packet rings intersect each other. The invention is easy to be implemented. It has good compatibility with the existing networks. Its cast is very low.
