Typical core-edge topologyResilient FabricsA resilient core-edge topology simply means that the core switches arein a redundant configuration, as shown in Figure 22, making the fabricdesign more resilient to a failure of a core switch. The typical resilientfabric has two core switches with multiple edge switches connected toboth core switches. In the event of a core switch failure, there is analternative path from any edge switch to the other core switch.40 Securing Fibre Channel Fabrics
