When I read juniper document about show route:
I show route IP:
admin@MX480> show route 184.108.40.206 inet.0: 837234 destinations, 1784889 routes (832157 active, 0 holddown, 862249 hidden) + = Active Route, - = Last Active, * = Both 220.127.116.11/21 *[BGP/170] 6w4d 23:44:08, localpref 132 AS path: 58931 I, validation-state: unverified > to 18.104.22.168 via gr-3/1/10.8 [BGP/170] 2w6d 10:12:47, MED 10, localpref 110 AS path: 3257 174 I, validation-state: unverified > to 22.214.171.124 via ae5.0 [BGP/170] 1w3d 11:23:37, localpref 105 AS path: 4809 4134 I, validation-state: unverified > to 126.96.36.199 via ae2.0
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
188.8.131.52/21 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?
Last Active meaning? is it mean to a destination, the last route usage is it, right?
why the example
184.108.40.206/21 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?
