The IP NULL DPO represents the rubbish bin for IP traffic.
Without specifying an action (i.e. send IMCP type X to sender) it is equivalent to using a drop DPO. However, in contrast to the drop DPO any route that resovles via a NULL, is considered to 'resolved' by FIB, i.e. a IP NULL is used when the control plane is explicitly expressing the desire to drop packets. Drop DPOs are used internally by FIB when resolution is not possible.
Any replies to sender are rate limited. Actions to take when a packet encounters the NULL DPO
