| Video Discription | Network redundancy is the ability of the network to survive failure of a single path, or multiple paths, and maintain connectivity. Routers provide redundant paths for available networks; switches provide redundant paths in a switched environment. Redundancy can increase capacity and reliability. Spanning Tree Protocols (STPs) are designed to support multiple Layer 2 paths in a switched network, while preventing loops at Layer 2. Another form of redundancy in switched networks makes it possible for hosts to use alternate default gateways. If a multilayer switch or router serving as a default gateway fails, the hosts associated with this default gateway become isolated from outside networks. First-hop redundancy protocols enable hosts to automatically fail over to alternate default gateways should one of them become unavailable. |
