This read-write object classifies the route's type: local, where the next hop is the final destination; remote, where the next hop is an intermediate router; or reject, a route that discards matching traffic as unreachable, often used for route aggregation. Admins use reject routes to correctly summarize a block of addresses while explicitly dropping traffic to unallocated sub-ranges within that block, rather than silently black-holing or mis-forwarding it. Setting zhIpCidrRouteType to reject(2) for an aggregate route covering an unused address block would cause the device to discard packets destined for that unallocated range as unreachable, rather than forwarding them incorrectly.
