Hello, I want to know that why bridges are integrated. So, I saw that GRE tunnels also established on br-int. I dumped flowtables on br-int like bellow. (It's summerized ) ________________________________ table=0, n_packets=29, n_bytes=2938, send_flow_rem in_port=3,dl_src=fa:16:3e:9e:dc:5f actions=set_field:0x3->tun_id,goto_table:10 table=0, n_packets=22, n_bytes=2308, send_flow_rem in_port=4,dl_src=fa:16:3e:41:24:1d actions=set_field:0x3->tun_id,goto_table:10 table=0, n_packets=70, n_bytes=8286, send_flow_rem tun_id=0x3,in_port=2 actions=goto_table:20 table=0, n_packets=0, n_bytes=0, send_flow_rem priority=8192,in_port=3 actions=drop table=0, n_packets=0, n_bytes=0, send_flow_rem priority=8192,in_port=4 actions=drop table=0, n_packets=415, n_bytes=37765, send_flow_rem dl_type=0x88cc actions=CONTROLLER:56 table=10, n_packets=0, n_bytes=0, send_flow_rem priority=8192,tun_id=0x3 actions=goto_table:20 table=10, n_packets=12, n_bytes=1860, send_flow_rem priority=16384,tun_id=0x3,dl_dst=01:00:00:00:00:00/01:00:00:00:00:00 actions=output:2,goto_table:20 table=10, n_packets=24, n_bytes=2084, send_flow_rem tun_id=0x3,dl_dst=fa:16:3e:4c:a5:a9 actions=output:2,goto_table:20 table=10, n_packets=15, n_bytes=1302, send_flow_rem tun_id=0x3,dl_dst=fa:16:3e:e8:f6:86 actions=output:2,goto_table:20 table=20, n_packets=39, n_bytes=3386, send_flow_rem priority=8192,tun_id=0x3 actions=drop table=20, n_packets=21, n_bytes=2956, send_flow_rem priority=16384,tun_id=0x3,dl_dst=01:00:00:00:00:00/01:00:00:00:00:00 actions=output:4,output:3 table=20, n_packets=18, n_bytes=2102, send_flow_rem tun_id=0x3,dl_dst=fa:16:3e:41:24:1d actions=output:4 table=20, n_packets=25, n_bytes=2732, send_flow_rem tun_id=0x3,dl_dst=fa:16:3e:9e:dc:5f actions=output:3 ________________________________ Then, I assumed that by enabling OF1.3 protocol on OVS, they can use pipe-lining method by numbering Flowtable. But, I could not know that what is the advantage of integration of both bridges There are any performance improvement? and second question is that packets which are putted tunnel are already transmitted to other host by marked flow-table why it is addressed by "table=20"?
