Embodiment 1
[0033] see figure 2 , figure 2 It is a schematic diagram of implementation of Embodiment 1 provided by the present invention. exist figure 2 Among them, ports Port1_1, Port2_2, Port3_3, and Port4_4 of the switching device are in the same chipChip1_1. Port1_1 and Port4_4 belong to MDC1_1, and Port2_2 and Port3_3 belong to MDC1_2.
[0034] exist figure 2 Among them, Port1_1, Port2_2, Port3_3, and Port4_4 all belong to VLAN1_1.
[0035] Take host 1 accessing host 4 on the second layer as an example, then,
[0036] Such as figure 2 As shown, the switching device receives layer 2 (data link layer) packet 1_1 through Port1_1. The source MAC address of the message 1_1 is the MAC address MAC1_1 of the host 1, and the destination MAC address is the MAC address MAC4_4 of the host 4.
[0037] The switching device maps MDC1_1 to which Port1_1 belongs and VLAN1_1 to which Port1_1 belongs to a VSI. For the method of dividing MDC based on ports in this embodiment 1, under this...
Embodiment 2
[0070] see image 3 , image 3 It is a schematic diagram of implementation of Embodiment 2 provided by the present invention. exist image 3 Among them, ports Port1_1, Port2_2, Port3_3, and Port4_4 of the switching device are in the same chip Chip1_1. Port1_1 and Port4_4 belong to MDC1_1, and Port2_2 and Port3_3 belong to MDC1_2.
[0071] exist image 3 Among them, Port1_1, Port2_2, Port3_3, and Port4_4 all belong to VLAN1_1.
[0072] Take host 1 accessing host 4 at Layer 3 as an example,
[0073] Such as image 3 As shown, the switching device receives layer-3 (network layer) packet 5_5 through Port1_1. Packet 5_5 is sent from host 1 to host 4, the source IP address is IP1_1, and the destination IP address is IP4_4.
[0074] The switching device maps the MDC1_1 to which Port1_1 belongs and the VRF1_1 to which packet 5_5 belongs to a VRF. For the method of dividing MDCs based on ports in Embodiment 2, in this method, the three-layer entries under different MDCs may be...

Abstract
The application provides a method and an apparatus for realizing a multi-tenant device context MDC based on the ports of a switching device. In the application, MDC not only participates in the mapping of VLAN and VSI, but also participates in the matching of three-layer entries, which means that both two-layer entries and three-layer entries in the configuration of MDC are associated with MDC. Amode of MDC division based on ports is realized. The restrictions on MDC port division with chips as units are broken. MDC configuration conflict between different MDCs on the same chip is avoided.
Description
technical field [0001] The present application relates to network communication technologies, and in particular to a method and device for realizing a multitenant device environment (MDC: Multitenant Devices Context) based on ports of switching devices. Background technique [0002] A physical device is divided into multiple logical devices through virtualization technology, and each logical device is generally called an MDC at present. Each MDC has an MDC configuration that supports its own operation, and the MDC configuration includes hardware resources and software resources. Hardware resources such as independent interfaces and CPUs, and software resources such as routing entries and forwarding entries. Each MDC has an independent startup file and configuration file, and its creation, operation, restart, and deletion will not affect other MDCs. [0003] There will be conflicting MDC configurations between different MDCs. In order to avoid conflicting MDC configurations...
