the ECMP Load Balancing Method to
Spillover .
The Spillover Threshold value is calculated
in kbps (kilobits per second). However, the
bandwidth on interfaces is calculated in kBps
(kilo Bytes per second).
For wan1 interface, Spillover Threshold = 100
kbps = 100000 bps. Assume that 1000 bps
is equal to 1024 bps. Thus, 100000 bps =
102400 bps = 102400/8 Bps = 12800 Bps.
