[j-nsp] BGP Hold-times

[Clinton Work]

If you only have a few BGP sessions with under 100 routes then I'm sure 
you can get away with 1 and 3 BGP timers. I have personally encountered 
problems with aggressive BGP timers on large scale MPLS PEs.  When the 
RP is handling hundreds of BGP sessions with thousands of routes the use 
of aggressive BGP timers can make some sessions unstable. If you really 
need fast convergence then BFD or a link state routing protocol would be 
a better choice.
