of 0.996. The correlation between memory use for networks and path entries is
insignificant in this case. (The data isn't shown; from now on, only significant regressions
are mentioned.)

Memory Use for BGP Paths
Figure 2-9 shows the memory used to store all the BGP path entries in the BGP RIB. The
Regression line is
memory (in bytes) = -20726.5 + 44.0 path entries
with an R
2
of 1.000.
