The BGP-4 ARO Path Attribute Unknown Table contains the per network path (NLRI) data on the path attributes advertised with a route but not known to the local BGP implementation or not otherwise capable of being returned from this agent. The absence of row data for a given index value for bgpAROPathAttrUnknownType indicates a lack of such unknown attribute information for the indicated network path. This table reports transmitted routes and path attributes after export policy has been applied. Only routes accepted by export policy are reported.
