Because route circularly flush route cache (/proc/net/sys/ipv4/route/secret_timeval),the multi-path route can't keep long time connections. The long time connections maybe interrupt every "secret_timeval" seconds. Such as: default nexthop via 192.168.0.1 weight 1 via 192.168.1.1 weight 1 via 192.168.2.1 weight 1 With a connection cross 192.168.0.1 in the first time."secret_timeval" seconds later,this connection maybe cross 192.168.1.1,then this connection will be reconnect. Anyone can help me?
