    Last Updated:Mar 25, 2024

    Disassociates the route table of an Enterprise Edition transit router from a prefix list.

    Operation description

    After you disassociate a route table of an Enterprise Edition transit router from a prefix list, the routes that point to the CIDR blocks in the prefix list are automatically withdrawn from the route table. Before you disassociate the route table of an Enterprise Edition transit router from a prefix list, you must migrate workloads that use the routes in case services are interrupted.

    Debugging

    OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer.
