//! Adds an internal interface to a logical router. This means a specified
//! subnet is attached to a router as an internal router interface.
//!
//! Specify the ID of a subnet or port in the request body:
//!
//! When you specify an IPv6 subnet, this operation adds the subnet to an
//! existing internal port with same network ID, on the router. If a port with
//! the same network ID does not exist, this operation creates a port on the
//! router for that subnet.
//!
//! The limitation of one IPv4 subnet per router port remains, though a port
//! can contain any number of IPv6 subnets that belong to the same network ID.
//!
//! When you use the `port-create` command to add a port and then call
//! `router-interface-add` with this port ID, this operation adds the port to
//! the router if the following conditions are met:
//!
//! If you specify both subnet ID and port ID, this operation returns the
//! `Bad Request (400)` response code.
//!
//! If the port is already in use, this operation returns the `Conflict (409)`
//! response code.
//!
//! This operation returns a port ID that is either:
//!
//! After you run this operation, the operation sets:
//!
//! Normal response codes: 200
//!
//! Error response codes: 400, 401, 404, 409
