Introduction Same or similar YANG types are used in the routing area YANG models Defined multiple times in individual models Definitions not Consistent These common types are collected and defined in this model In a sharable module Should be imported in routing area models Ensures consistent definitions for common routing types Analogous to ietf-yang-types but types specific to routing area

Next Steps Align with other models Solicit comments Additional common routing types for initial model? WG adoption Most useful if it progress at the same cadence as first wave of routing models.
