Strategy routing is a goal than routed based on network more flexible packet routing forwarding mechanism. Application strategy routing, router will decide how by routing graph of the packet processing requires routing, routing figure decided a packet forwarding the next-hop router.
Application strategies must be specified strategy routing, use routing figure, routing and will create route map. A routing figure composed by several strategies, each strategy defines one or more of the matching rules and corresponding operation. An interface application strategies to the routing after receiving all packages of interface to inspect, do not accord with routing figure any strategy according to the packet will usually routing forwarding processing, accord with a particular strategy routing diagram according to this packet is defined operation strategy for processing.
Strategy routing can make packets designated strategy according to user traffic. For some management purposes, such as QoS requirements or VPN topology, requires certain routing must pass a certain path, can use strategy routing. For example, a strategy can appoint issued from a network of packet forwarding to a particular only the interface.
Strategy routing species
Roughly divided into two kinds: one kind is the destination address of according to the routing to strategy called: the destination address routing;
Another kind is according to the routing source address for strategy implementation called: the source address routing!
Along with the development of strategy routing now has the third routing ways: intelligent equilibrium strategy way!
