[MT-AU Public] BGP sessions on a CCR2004

Hello all, I'm currently in the process of establishing an iBGP session between a VyOS router and a CCR2004 (which is being used to terminate NBN services) and I'm encountering an issue with routing tables. The CCR is taking an awfully long time to drain the routes that it has learnt, after we had to down the session due to a misconfiguration. It is taking hours upon hours to process the table and drop the routes. Is there a way (short of rebooting the router) to help drain the routes in a more timely manner? Further to this, what should we be selecting in the input and output affinity fields to help divide the load between all cores and reduce the strain? Regards, Christopher Hawker
