Parameters
multiplier Specifies an integer that sets the multiplier for the hello holding time.
Never configure a hello-multiplier lower than the default (3). The
range is from 3 to 1000. The default is 3.
level-1 (OPTIONAL) Select this value to configure the hello multiplier
independently for Level 1 adjacencies. This value is the default.
level-2 (OPTONAL) Select this value to configure the hello multiplier
