What Are the Differences Between Static BGP and Dynamic BGP?

The EIP type cannot be changed. For example, dynamic BGP EIPs cannot be changed to static BGP EIPs because they are in different IP address pools.

The differences between static BGP and dynamic BGP are as follows:

**Table 1** Differences between static BGP and dynamic BGP
Item	Static BGP	Dynamic BGP
Definition	Static routes are manually configured and must be manually reconfigured anytime when the network topology or link status changes.	Dynamic BGP provides automatic failover and chooses the best path based on the real-time network conditions and preset policies.
Assurance	When changes occur on a network that uses static BGP, the manual configuration takes some time and high availability cannot be guaranteed. NOTE: If you select static BGP, your application system must have disaster recovery setups in place.	When a fault occurs on a carrier's link, dynamic BGP will quickly select another optimal path to take over services, ensuring service availability.
Service availability	99%	99.95%

For more information about service availability, see Huawei Cloud Service Level Agreement.
