  • Redundant Linking Methods for Core Switches

    Redundant Linking Methods for Core Switches

    Parallel Redundancy Protocol (PRP) and High-Availability Seamless Redundancy (HSR) are two technologies that provide seamless transmission even when part of the network fails. According to the CORE's model, you should configure the two CORE as ONE CORE by using vPC, Stackwise or VSS technologies. In the event that one link fails, the secondary (or tertiary) link can take over, maintaining network uptime. This redundancy can be applied at various levels, including WAN connections.
