詳細描述

A routing indication is sent by a KNXnet/IP router or device to transmit KNX link layer frames over IP networks.

The common way to create a routing indication is:

QKnxLinkLayerFrame linkFrame = // create a link frame ....;
auto netIpframe = QKnxNetIpRoutingIndicationProxy::builder()
    .setCemi(linkFrame)
    .create();

If a KNXnet/IP router or device receives a router busy message from another router or device, it immediately stops sending routing indication frames and waits until the time specified in the router busy message has elapsed to resume sending frames.
