Thank you for confirming this. I was expecting it. I have done this in the past with a static route where the BGP origin is specified. I guess, this is not something that you plan to implement in future releasesNo, there is no option to set origin in filters. You can only force 'igp' by adding bgp network or set specific origin on static routes.
Because the summarization function of BGP didn't work for me and I created an unreachable static route, which than I advertise via "redistribute static". It's crazy I know, but this is the only option that actually worked and I didn't bother to poke with this since I've configured it.Out of curiosity, why not just use the network statement to originate the prefix properly?
