BGP propagation time

Thu Jul 12, 2018 5:52 pm

Hi,
I have 2 CCR:
1036em - BGP Edge
1008 - BRAS
They are connected via eBGP. When I connect client to BRAS via PPPoE - new route on 1036 is visible after ~70 sec. What can i do with it?

Full tables? That's all you can do, unfortunately. The BGP implementation isn't amazing (constant scanning of tables), single-core, and the CCR's individual cores are not amazing for computation.

Alternatively look at this excellent EU MUM talk for how to use CHR on 64-bit Intel for higher convergence speeds: https://mum.mikrotik.com/presentations/ ... 562405.pdf

Maybe make a separate BGP instance for internal routing?
I use BGP only there and for me it is fast. But I don't have internet tables.

Excuse my ignorance, dont have any experience with pppoe bras, but if you have just two devices, why you dont just make static aggregated route to your bras?
