We've applied an RA guard at the core. Would you mind checking to see if you are still seeing RA's, Ole?

I see no rouge RAs on ietf-a now.

thank you very much for the quick resolution!

no chance you can find the perpetrator? it would be very interesting to hear what software and configuration he has, assuming this is accidental.

cheers,
Ole
