my inquiry was very specific and bounded to the following assumptions:
- in-band management
- not possible to filter customer traffic, certainly not for somebody
In this case diffserv can help prioritize management plane traffic over
user traffic. To do that only ipp6 and ipp7 values are available for non
IPP6 is used by default for routing protocols, that is control plane; so
probably it is better not to mess around with it.
This leaves to IPP7 for management plane traffic, value that I can not
recall of having seen used by any application/protocol.
What is the general opinion about this?
