Prefix Count
The input packet drops fell to 0, so they were removed from the graph. The convergence
time with optimized queues decreases by 12% when compared to just peer groups.
Pre-Release 12.0(19)S Feature Comparison
Figure 3-11 compares decreases in convergence time for the various feature combinations.
This graph shows the impact of stacking the BGP convergence features. The improvement
over peer groups for deploying both PMTUD and queue optimization is a 29% decrease in
convergence time on average.
Figure 3-12 compares a fully optimized pre-Release 12.0(19)S router and the baseline
convergence.
The available features before Release 12.0(19)S provide a decrease in BGP convergence
time of 45% over the default configuration. This increase in BGP performance is available
as early as 12.0(13)S.
