[c-nsp] BGP timer jitter?

[bored to death]

hi everybody,

 i was monitoring cisco's BGP packets and i realized my cisco's BGP keepalive 
packets are being sent out exactly every 60 seconds (with no jitter - with 
maximum 0.001 seconds variance).i looked at BGP main RFC (RFC4271) and it says 
timers should have jitters and says:

"[...] jitter SHOULD be applied to the   timers associated with 
MinASOriginationIntervalTimer, 
KeepaliveTimer,MinRouteAdvertisementIntervalTimer, and ConnectRetryTimer. [....] 
The suggested default amount of jitter SHALL be determined by   multiplying the 
base value of the appropriate timer by a random factor, which is uniformly  
distributed in the range from 0.75 to 1.0.    A new random value SHOULD be 
picked each time the timer is set."

so i wanted to know, has cisco implemented timer jitters for different timers (5 
timers) of BGP? if so, do i have to do anything to activate it?

Cheers!
