A hm2AgentDvmrpNeighborLoss trap signifies the loss of a 2-way
adjacency with a neighbor.  This trap should be generated
when the neighbor state changes from active to one-way,
ignoring, or down.  The trap should be generated only if the
router has no other neighbors on the same interface with a
lower IP address than itself.

A hm2AgentDvmrpNeighborNotPruning trap signifies that a non-pruning
neighbor has been detected (in an implementation-dependent
manner).  This trap should be generated at most once per
generation ID of the neighbor.  For example, it should be
generated at the time a neighbor is first heard from if the
prune bit is not set in its capabilities.  It should also be
generated if the local system has the ability to tell that a
neighbor which sets the the prune bit in its capabilities is
not pruning any branches over an extended period of time.
The trap should be generated only if the router has no other
neighbors on the same interface with a lower IP address than
itself.
