When I read juniper document about show route:
I show route IP:
admin@MX480> show route 14.104.112.1
inet.0: 837234 destinations, 1784889 routes (832157 active, 0 holddown, 862249 hidden)
+ = Active Route, - = Last Active, * = Both
14.104.112.0/21 *[BGP/170] 6w4d 23:44:08, localpref 132

I have several questions:
1.what's the destinations meaning ? in document it say Number of destinations for which there are routes in the routing table.
you see in routing table there have 14.104.112.0/21
in it, the destinations number is 2048 or 1?
2.you see the 1784889 routes (832157 active, 0 holddown, 862249 hidden)
, why 1784889 != 832157 + 0 + 862249
?
3.what's the Last Active
meaning? is it mean to a destination, the last route usage is it, right?
why the example 14.104.112.0/21
there have 3 routes, but only one active? why the other two do not active? is it only one route for a special destination by default?
