I don't think JunOS supports this. It's bit of hack at any rate. It's not transporting AS_PATH, it's transporting single 16b ASN. It's essentially abusing (some what well-defined and interoperable abuse) 32b tag field for this purpose. Maybe you could try to do some of this manually, set some tags, which trigger 'set then origin x', as-path-expand/prepend might be more challenging. Recommendation for solution might be easier with rationale why you need to transport origin+aspath over IGP. -- ++ytti
