我在Ubuntu LTS 14.04.2上使用mininet在我的计算机上设置了一个网络。我有一个OVS交换机，启用了ip转发，用于inter-vlan路由，我在这个交换机上安装了一些策略和路由。安装在除main之外的其他表中的路由会自动被删除。
这些是我安装的政策。

32766: from all lookup main
32767: from all lookup default
这些是我的主表中安装的用于VLAN间路由的路由
10.0.1.0/24 dev vlan11 proto kernel scope link src 10.0.1.251
10.0.1.0/24 dev vlan21 proto kernel scope link src 10.0.1.252
10.0.1.0/24 dev vlan31 proto kernel scope link src 10.0.1.253
10.0.1.0/24 dev vlan41 proto kernel scope link src 10.0.1.254
10.0.2.0/24 dev vlan12 proto kernel scope link src 10.0.2.251
10.0.2.0/24 dev vlan22 proto kernel scope link src 10.0.2.252
10.0.2.0/24 dev vlan32 proto kernel scope link src 10.0.2.253
10.0.2.0/24 dev vlan42 proto kernel scope link src 10.0.2.254
10.0.3.0/24 dev vlan13 proto kernel scope link src 10.0.3.251
10.0.3.0/24 dev vlan23 proto kernel scope link src 10.0.3.252
10.0.3.0/24 dev vlan33 proto kernel scope link src 10.0.3.253
10.0.3.0/24 dev vlan43 proto kernel scope link src 10.0.3.254
10.0.4.0/24 dev vlan14 proto kernel scope link src 10.0.4.251
10.0.4.0/24 dev vlan24 proto kernel scope link src 10.0.4.252
10.0.4.0/24 dev vlan34 proto kernel scope link src 10.0.4.253
10.0.4.0/24 dev vlan44 proto kernel scope link src 10.0.4.254
分别是表2,3,4,5的路线
10.0.0.0/16 dev s1-eth1 table 2 proto static scope link
10.0.0.0/16 dev s2-eth1 table 3 proto static scope link
10.0.0.0/16 dev s3-eth1 table 4 proto static scope link
10.0.0.0/16 dev s4-eth1 table 5 proto static scope link
问题是表2,3,4,5中的这些路由会在设置的几分钟内自动删除。主要工作路线很好。
