ccna discovery

ccna discovery

The implicit empty tag above has already been introduced, it does increase efficiency, but there is also a problem,ccna discovery, because if I receive an implicit null tag sent by a downstream neighbor about a particular prefix bundle, then I am forwarding the tag. Before the data is given to the neighbor, I will first pop the top-level label. Then the pop-up action actually pops up the entire top-level label header, that is, even the fields with the label field, EXP, etc. pop up, and EXP knows For QoS , it is also popped up, meaning that some information for QoS is lost here .
