The value of vRtrInetAggrNextHopType specifies whether the aggregate
route will be installed in the Forwarding Information Base (FIB) when
the route is activated.
When vRtrInetAggrNextHopType has a value of 'none', the aggregate route
will not be installed in the FIB.
When vRtrInetAggrNextHopType has a value of 'blackHole' and the
aggregate route is active, it will be installed in the FIB with a
black-hole next-hop and packets matching this route will be discarded.
