Also, the dampening defaults:
bgp dampening <halflife-time> <reuse> <suppress> <maximum-suppress-time>
<halflife-time> default is 15 minutes
<reuse-value> default is 750
<suppress-value> default is 2000 (I thought it was 1000, but docs indicate
otherwise)
<max-suppress-time> default 4 times halflife-time
