This is the type of this IP Reachable Address, following the ManualOrAutomatic behavior; manual entries are created by the network manager and automatic entries through propagation of routing information from another protocol. This is the IP-specific counterpart to ciiRAType, carrying the same operational implication that an automatic entry was injected by redistribution and will likely regenerate or resist manual editing. For example, an admin repeatedly deleting an IP reachable-address entry only to see it reappear each polling cycle would find, on checking this field, that it is marked automatic and thus being continuously regenerated by an active redistribution policy elsewhere.
