DRAG DROP Drag and drop the LDP features from the left onto the descriptions on the right 
Session establishment should be separate from neighbor discovery because it involves setting up the control channel, not just finding the peer. Label distribution definitely fits with mapping since it’s about exchanging label info after the session is up.
I’d put the session establishment under the discovery phase too, since without session there’s no label exchange. Label mapping seems more like the actual label info transfer after discovery.
For me, the label distribution feature fits best with mapping since it’s about sending and receiving label info. Discovery is more about establishing the initial connection between routers.
For sure, discovery pairs best with neighbor discovery since that’s how routers find each other first.
I think the discovery feature should be matched with neighbor discovery since it’s what helps routers find each other before labels are assigned. The session part is more about label mapping and exchange.
I’d pick the feature about label distribution for the session description since LDP mainly handles label mappings. The discovery process seems more about neighbor info, so that matches another feature better.
Not sure how to drag here, but I'd say B fits the session point.
