Distributed Virtual Routing (DVR) is a powerful capability available with Extreme Fabric Connect. It enables a single tier routing architecture for distributed Fabric-based networks. It distributes the routing function (virtual default gateway) so that it is always available at first network hop. As a result, any wired, wireless or virtual host can physically move to any point in the network fabric while benefiting from shortcut switching and routing.
With this technology, tromboning is avoided, performance is enhanced, and traffic flows are optimized. It is applicable for Data Center deployments, Data Center Interconnect deployments and Campus networks, especially wireless deployments to optimize client roaming.
