This object specifies which route types a BGP or OSPF routing policy should match and filter, such as locally generated routes, external routes, or routes of a specific type (e.g., OSPF external type 1 vs. type 2). By restricting policy application to specific route types, administrators can apply different forwarding treatments and route propagation rules based on the origin and classification of the route. Network operators use this configuration when designing multi-protocol routing policies to ensure that different sources of routing information are handled according to security and performance requirements.
