ovs 流表机制(二)-OVS流表table之间的跳转

1、把所有的flow删掉

[root@kunpeng82 devuser]# ovs-ofctl dump-flows vswitch0 table=0
cookie=0x0, duration=132.837s, table=0, n_packets=0, n_bytes=0, priority=1,in_port="tap0_br" actions=output:"tap3_br"
cookie=0x0, duration=127.745s, table=0, n_packets=0, n_bytes=0, priority=1,in_port="tap3_br" actions=output:"tap0_br"
[root@kunpeng82 devuser]# ovs-ofctl dump-flows vswitch0 table=1

[root@kunpeng82 devuser]# ovs-ofctl del-flows vswitch0
[root@kunpeng82 devuser]# ovs-ofctl dump-flows vswitch0
[root@kunpeng82 devuser]#

2、在table 1增加两条flow
[root@kunpeng82 devuser]# ovs-ofctl add-flow vswitch0 "table=1,priority=1,in_port=2,actions=output:1"
[root@kunpeng82 devuser]# ovs-ofctl add-flow vswitch0 "table=1,priority=2,in_port=1,actions=output:2"
还是不通哦

[root@kunpeng82 devuser]# ip netns exec ns1 ping 192.168.1.200
PING 192.168.1.200 (192.168.1.200) 56(84) bytes of data.

From 192.168.1.100 icmp_seq=2 Destination Host Unreachable

^C

pipe 4

给table 0 添加一条跳转到table 1的flow

[root@kunpeng82 devuser]# ovs-ofctl add-flow vswitch0 "table=0,actions=goto_table=1"
可以ping通了

[root@kunpeng82 devuser]# ip netns exec ns1 ping 192.168.1.200
PING 192.168.1.200 (192.168.1.200) 56(84) bytes of data.
