The following limitations and restrictions apply to the Cisco BWG feature in Cisco IOS Release 
12.4(24)YG1:

To avoid issues with high CPU usage, we recommend the following configurations:

To reduce the CPU usage during bootup, disable logging to the console terminal by configuring 
the no logging console global configuration command.

To ensure that the HSRP interface does not declare itself active until it is ready to process a peers 
Hello packets, configure the delay period before the initialization of HSRP groups with the 
standby delay minimum 100 reload 100 interface configuration command under the HRSP 
interface.
