Usage Guidelines

At a minimum interval, VPC vs non-VPC cases, and also with single vs dual sup cases, Basically for vPC and with dual sups one needs to use default timers. the neighbor hold time is automatically set to 3.5x this value. Also it is recommended to use BFD for PIM instead of non-default timers.
