OSPF doesn't delete "routes", it sends LSAs. It seems that you are redistributing a lot of single IP addresses in OSPF (as external routes). So there's one LSA type 5 for each single redistributed /32.
OSPF is not the proper choice for this usecase, and it's not a Quagga or BIRD issue. BGP is the protocol to use for such cases. Many routes, few messages, scalability. > Le 14 juil. 2015 à 09:20, Andrew <ni...@seti.kr.ua> a écrit : > > When routes are deleted (for ex., terminating a lot of PPP tunnels for some > reason in same time), it seems like each removed route is sent into separate > OSPF packet that causes troubles with OSPF in some cases (for ex., there's > troubles with old quagga). > > Is there a possibility to add some rate-limiting (for ex., limit to 10 > messages per second), and aggregate separate 'route deleted' messages to one > packet?
