Queries the associated forwarding correlations that are created for a route table of an Enterprise Edition transit router or a network instance connection.
Operation description
When you call ListTransitRouterRouteTableAssociations, you must set at least one of TransitRouterRouteTableId and TransitRouterAttachmentId.
-
If you set only TransitRouterRouteTableId, the network instance connections that are in associated forwarding correlation with a route table of an Enterprise Edition transit router are queried.
-
If you set only TransitRouterAttachmentId, the route table of an Enterprise Edition transit router that is in associated forwarding correlation with a network instance connection is queried.
-
If you set both TransitRouterRouteTableId and TransitRouterAttachmentId, the associated forwarding correlations between a specified network instance connection and a specified route table of an Enterprise Edition transit router are queried.
- If an associated forwarding correlation is created between the network instance connection and the route table of the Enterprise Edition transit router, the information about the associated forwarding correlation is returned.
- If no associated forwarding correlation is created between the network instance connection and the route table of the Enterprise Edition transit router, TransitRouterAssociations in the response is empty.
