acquiring and storing, by a designated logical router of the plurality of logical routers, shared information of the shared sub-port and the virtual sub-port, wherein the shared information is used to indicate at least one of: all the sub-ports that have been shared; and all the sub-ports which are shared respectively correspond to the logic routers, wherein all the sub-ports comprise at least one of the following: the shared sub-port, the virtual sub-port.
3. The method of claim 1, wherein prior to port sharing for multiple logical routers of the physical router based on the sub-port and the virtual sub-port, the method further comprises:
determining whether a sub-port to be shared and a board where the sub-port to be shared is located are exclusively owned by a logical router, wherein the sub-port to be shared includes: the shared sub-port and the virtual sub-port;
if yes, the sub-port to be shared forbids to continue sharing;
and if not, allocating the sub-ports to be shared.
4. The method of claim 3, wherein prior to allocating the sub-port to be shared, the method further comprises:
detecting whether the number of the logic routers distributed to the sub-ports to be shared exceeds a set threshold value;
if yes, the sub-port to be shared forbids to continue sharing;
and if not, allocating the sub-ports to be shared.
5. The method of claim 1, wherein after establishing a shared sub-port corresponding to a shared port of a physical router and a virtual sub-port corresponding to the shared sub-port, the method further comprises:
under the condition that it is detected that a sub-port to be shared needs to be exclusively shared by a logic router, determining whether the sub-port to be shared is shared by the logic router, wherein the sub-port to be shared comprises: the shared sub-port and the virtual sub-port;
if so, sending an instruction to a first logic router to instruct the first logic router to recycle the sub-port to be shared, wherein the first logic router shares the sub-port to be shared.
6. The method of claim 5, wherein after sending an instruction to the first logical router to instruct the first logical router to reclaim the sub-ports to be shared, the method further comprises:
and allocating the recovered sub-port to be shared to a second logic router for exclusive use.
7. A port sharing device, comprising:
the system comprises a creating module and a processing module, wherein the creating module is used for creating a shared sub-port corresponding to a shared port of a physical router and a virtual sub-port corresponding to the shared sub-port;
a sharing module, configured to perform port sharing for multiple logical routers of the physical router based on the sub-port and the virtual sub-port.
8. The apparatus of claim 7, wherein the sharing module is further configured to obtain and save, by a designated logical router of the plurality of logical routers, shared information of the shared sub-port and the virtual sub-port, wherein the shared information is used to indicate at least one of: all the sub-ports that have been shared; and all the sub-ports which are shared respectively correspond to the logic routers, wherein all the sub-ports comprise at least one of the following: the shared sub-port, the virtual sub-port.
9. A computer-readable storage medium, in which a computer program is stored, wherein the computer program is configured to carry out the method of any one of claims 1 to 6 when executed.
10. An electronic device comprising a memory and a processor, wherein the memory has stored therein a computer program, and wherein the processor is arranged to execute the computer program to perform the method of any of claims 1 to 6.
