Static BGP routing refers to the routing information by the network operator manual configuration, or when the topology of the network link status changes, operators need to manually to modify related static routing information in routing tables, static routing information is private by default, will not transfer to other routers, static routing generally suitable for simple network environment, In such an environment, carriers can easily understand the network topology and set correct routing information.
Dynamic BGP multiple wire network, routing table entries is through the mutual connections between the switches to exchange information, then according to certain algorithm is optimized, and the routing information is continuously updated in a certain time interval, to adapt to the changing network, at any time to obtain the optimal effect of pathfinding, in order to realize the efficient pathfinding of IP packet, IETF has developed a variety of pathfinding protocols
The real dynamic BGP can realize multi-network access with low latency, high efficiency, high stability, and low failure rate. However, the cost is relatively high. At present, some manufacturers in the market only provide users with multi-carrier access, which is called multi-line but not BGP bandwidth in the real sense. When a single point of failure occurs on a carrier link, routes cannot be reconnected across carriers
In other words, when the network structure of static BGP changes, carriers cannot automatically adjust the network Settings to ensure user experience. Dynamic BGP automatically optimizes the network structure based on the specified path finding protocol to ensure the stability and efficiency of customers’ networks
What are the advantages of dynamic BGP over static BGP?
Dynamic BGP advantage 1: Three carriers can implement redundancy among themselves and automatically select optimal paths to avoid single points of failure.
Advantages of dynamic BGP: Low latency, high efficiency, and better stability!
Advantage 3: Dynamic BGP is functional
1. Automatic collection of routing table: 800,000, self-optimization;
2. Maintain neutrality, eliminate barriers to north-south access, and be superior to neutral institutions above the three major operators;
3. Nearly doubled bandwidth utilization;
4, to provide rich routing policies, equivalent to automatic navigation function (water, land, air travel scheme automatic selection, the fastest, the most smooth);
5. Adopt authentication and GTSM to ensure network security (automatically consider abnormal packet sending requests);
6. Provides route aggregation and route attenuation functions to prevent route flapping;
7. BGP can be configured when the carrier network structure changes. Pathfinding protocol automatically optimizes the network routing structure in the first time to eliminate network blind spots.
8. Automatically select the optimal route according to the algorithm to reduce the hop count delay
