A1)
In DU mode, a LSR may receive FEC/Label mapping from multiple LSRs for the same FEC. Therefore, when operating in liberal retention mode, there may be multiple (peer, out label) entries.
A2)
Not always. It depends upon the configured label retention mode.
A3)
The one which comes from the next hop LSR for this FEC (Recall, LDP mimic the hop-by-hop IGP behaviour).
A4)
No. Because the upstream LSR makes an explicit label request from the downstream LSR (next hop for that FEC).
A5 )
No. Because LDP mimic the IGP paths.
A6)
Three. One adjacency per link.
