For those in multivendor environments, it's worth also being aware that sin=
ce 7.6R1 JunOS sets the minimum BGP hold timer to 20 seconds. If I were cre=
ating a standard timer config to deploy consistently on customer peers (and=
needed something on the fast side in timer terms) I would need to take tha=
t into account.
(And yes, there is of course a way to override the 20s hold timer, but it's=
not a supported config last time I checked)

60-180 is fairly conservative. 60-180 is the Cisco default I believe, howev=
er
Junipers defaults are 30-90. I never pissed anyone off with that ;)
