The value of tBgpInstanceMinHoldTime specifies the minimum hold time
that should be strictly enforced on tBgpInstanceHoldTime.
When the value of tBgpInstanceMinHoldTime is configured, BGP will not
negotiate a hold time lower than the configured value.
An 'inconsistentValue' error is returned if an attempt is made to set
this object to a value greater than tBgpInstanceHoldTime.
