Unlinking a Route Table from a Subnet

You can unlink a route table from a Subnet. This Subnet no longer uses the routes contained in this route table to route network trafic, but uses the routes contained in the main route table instead until you explicitly associate another route table to it.

Unlinking a Route Table from a Subnet Using OSC CLI

The UnlinkRouteTable command disassociates a Subnet from a route table.
After disassociation, the Subnet can no longer use the routes in this route table, but uses the routes in the main route table of the Net instead.
