Hi All I discover the following problem: FreeBSD host install route recived by ICMP-redirect from default GW and this route is permanents. In my case FreeBSD 192.168.1.10/24 has 192.168.1.254 as default gateway. This network has interconnection with remote network 192.168.88.0/24 via some other gateways -- 192.168.1.199 + 192.168.1.195 for example. All gateways using OSPF to exchange routing info. 192.168.1.10 send packet destined to remote network (192.168.88.0/24) to default gateway 192.168.1.254, receive ICMP-redirect and install route to 192.168.88.0/24 via 192.168.1.199. Then 192.168.1.199 off for some reason but 192.168.1.10 never know about it because route installed via 192.168.1.199 is permanent. I see net.inet6.icmp6.redirtimeout in my FreeBSD 11.2-STABLE #0 r339734 and I think this sysctl set timeout for routes installed via ICMP-redirects (route deletes after this timeout?). Is it possible to get such sysctl for ipv4 ? Thanks! -- CU, Victor Gamov
