What Are the Differences Between Static BGP and Dynamic BGP?

The differences between static BGP and dynamic BGP are as follows:
Table 1 Differences between static BGP and dynamic BGP

Aspect

Static BGP

Dynamic BGP

Definition

Static routes are manually configured and must be manually reconfigured any time the network topology or link status changes.

Dynamic BGP provides automatic failover and chooses the optimal path when a network connection fails.

Assurance

When changes occur on a network using static BGP, the manual configuration takes some time and high availability can't be guaranteed.

NOTE:

If you select static BGP, your application system must have the disaster recovery capability.

When a fault occurs on a carrier's link, dynamic BGP will quickly select another optimal path to take over services, ensuring service availability.

Currently, carriers in China that support dynamic BGP routing include China Telecom, China Mobile, China Unicom, China Education and Research Network (CERNET), National Radio and Television Administration, and Dr. Peng Group.
