Setting this object to the value invalid(2) has
the effect of invalidating the corresponding
entry in the ipForwardTable object. That is,
it effectively disassociates the destination
identified with said entry from the route iden-
tified with said entry. It is an
implementation-specific matter as to whether
the agent removes an invalidated entry from the
table. Accordingly, management stations must
be prepared to receive tabular information from
agents that corresponds to entries not current-
