My searches have come up a little short however I found a couple references to using automatic-tag and as-path tag to carry this through. I cant seem to find any Junos reference information on this so wanted to reach out to the ether and see if others have faced this situation before or have any other recommendations on solutions.
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
