This is an enumerated route type for an entry in the virtual router's route table, distinguishing other, reject, local, and remote routes, where local means the next hop is the final destination and remote means it is not. It tells an admin at a glance whether a given route entry will actually forward traffic (local or remote) or discard it as unreachable (reject). Seeing an unexpected reject-type entry for a customer's subnet in one virtual router's route table would explain why that subnet suddenly stopped being reachable.
