in conclusion:
Method 1: Configure the external priority of the BGP protocol to be higher than the priority of the static route, preferably BGP.
Advantages: Simple configuration.
Disadvantage: It takes effect globally. If the user wants to increase the priority of a static route and is not affected by the dynamic route, the priority needs to be artificially increased for each static route.
Method 2: Configure the external priority of the specified static route to be the same as the priority of the BGP protocol. Then, because the internal priority of EBGP is higher than that of the static route, the EBGP protocol is preferred.
Corresponding to the advantages and disadvantages of method one.

Configuration method:
Method 1: Configure BGP to take precedence over static routes.
Step 1: Check the priority of the destination network segment
Step 2: Modify the protocol priority of BGP to 50, which is higher than the static route

Step 3: Check the priority of the destination network segment
Method 2: When the external priority is the same, the EBGP priority is higher than the static route

Comments: The router first compares the external priorities of the routing protocols, and the routes learned by the protocols with higher external priorities are preferentially added to the routing table.
If the external priorities are the same, then the internal priorities of the protocols are compared, and the routes learned by the protocols with higher internal priorities are preferentially added to the routing table.
