Egyebkent ezt az elatkozott dolgot talaltam: https://blog.benjojo.co.uk/post/flexing-windows-rras-bgp-stack-ipv6, a poszt iroja az a Ben Cox akinek a https://bgp.tools websiteot is koszonhetjuk.

@Ben Cox:
After setting up two remote “routers” to emulate 2 carrier links and peering them with windows, I noticed that windows was consuming a pretty extreme amount of memory, and 4 to 6 entire CPU cores:

Checking what service the process matched with, and yep, it’s RRAS.

Ertsd: olyan fos a mikrofos-fele BGP implementacio, hogy hasznalhatatlan, sokat zabal (meg a BGP-hez kepest is!).

@Ben Cox:
Unfortunately RRAS is also completely unresponsive to outside input during this, meaning we cannot easily query what it thinks about some routes, some sessions even stopped getting KEEPALIVE from windows, suggesting that in a real world setup they would just trigger the BGP HoldTimer Expiry mechanism.

Ez meg azert fontos, mert ha eldoglik a BGP-d, akkor kiesik a hirdetesed a route tablakbol, ezaltal elerhetetlenne teszik a halozatod. Pl. egy BIX-ben egy ilyen vagy ehhez hasonlo parameterekkel rendelkezo router az a tulzas kategoria (asszem'), atlagban 4-6 cpu mag meg 4gb ram boven eleg szokott lenni erre a hardcore taszkra.

Kecskebaszók ide!
