Summary0008328: Need for clarification on the usage of the networkInterface part of the Address structure.
Description

In the sections under [7.3.2 OPC UA UDP], usage of the url part of the Address structure is well described. But there is a complete silence about the networkInterface part. Some clarification may be added there.

For example for UDP Unicast Publisher (where the destination Address is configured on the WG level), specifying the networkInterface doesn't make sense, as the outbound interface is selected by the network stack. Should there be an error if the networkInterface is specified anyway?

For UDP Unicast Subscriber, it may be written, that in case the networkInterface is not specified (NULL or empty string), then the Subscriber listens on all interfaces.

Additionally, explicitly specifying network interface seems to be mandatory in case the IPv6 link local addresses are used.

Added following clarification for 7.3.2.2 UDP multicast and broadcast
The NetworkInterface field in the Address is required if more than one network interface is available.

Added following clarification for 7.3.2.3 UDP unicast
Connection:
The NetworkInterface field in the Address is not required and is only configured if the Subscriber should listen only on one interface.
WriterGroup:
The NetworkInterface field in the Address is not required and shall be null or empty.
