Hello, back again on this topic. This problem is still not completely fixed with Debian Bullseye and kernel 5.10.46. The workaround is still: net.ipv6.route.max_size = 400000 net.ipv6.route.gc_thresh = 102400 On https://bird.network.cz/pipermail/bird-users/2020-March/014406.html is mentioned that you can also set: net.ipv6.route.gc_thresh = -1 But is this value save to use? This is also the default for IPv4: net.ipv4.route.gc_thresh = -1 With the default value of net.ipv6.route.gc_thresh = 1024 we have still much jitter on the line. Why is still the default value of net.ipv6.route.max_size still 4096? Compared to IPv4 value: net.ipv4.route.max_size = 2147483647 Has someone done more research on this topic? Best regards, Oliver
