dampening

Task: After a prefix flaps two times in a row, the advertisement should resume in 5 minutes.

I created the loopback, and shut/unshut it twice (as per above requirement) - on R3, this did not cause the route to be dampened.

R3#sh ip bgp 1.1.1.1
BGP routing table entry for 1.1.1.1/32, version 114
Paths: (1 available, best #1, table default)
Flag: 0x820
  Advertised to update-groups: (Pending Update Generation)
     2          3
  Refresh Epoch 1
  100
    155.1.13.1 from 155.1.13.1 (150.1.1.1)
      Origin IGP, metric 0, localpref 100, valid, external, best
      Dampinfo: penalty 1857, flapped 2 times in 00:00:37
      rx pathid: 0, tx pathid: 0x0

It took 3 attempts.   Also, flap-statistics show that the adv wont resume in 5min?

    Network          From            Flaps    Duration  Reuse      Path
*d  1.1.1.1/32       155.1.13.1      3     00:02:1700:06:10 100

The verbiage in the SG left me scratching my head.  If anyone has any input that would be great - I'm going back to the books for this.
