Option D is definitely wrong. The whole point of downstream unsolicited is that the LER doesn't wait for a request before sending out the label mapping. B is the clear winner here.

Option B is the correct choice. Downstream unsolicited label distribution involves advertising label mappings to potential next-hops without waiting for a request.

Haha, downstream unsolicited label distribution? Sounds like my ex-girlfriend trying to set me up with all her friends, whether I asked for it or not!

I'm torn between B and C, but I think B is the more accurate description. The LER doesn't need to wait for a label from the next-hop before advertising its own label mapping.

Option B seems to describe the concept of downstream unsolicited label distribution the best. The LER proactively advertising label mappings to all potential next-hops is the key characteristic of this mechanism.
