Hi,
I assume the following situation.
* HOST1
br-ex :
tap8899056d-35 ---:-- qg-8899056d-35
:
br-int :
tapa6339ea8-4d ---:-- qr-a6339ea8-4d
:
: netns = qrouter-XXXX
- - - - - - - - - -
tap06848d58-32 ------ dhcp
qvoaa57e45b-26 ------ vm1
qvo0c3ff3ef-ad ------ vm2
grec0a8000b-c0 ---+
|
|
* HOST2 |
|
br-int |
grec0a8000a-c0 ---+
qvoae30579c-93 ------ vm3
The ports of br-int of HOST1 are as follows.
port 0: br-int (internal)
port 1: tap06848d58-32
port 2: tapa6339ea8-4d
port 3: qvoaa57e45b-26
port 4: qvo0c3ff3ef-ad
port 5: grec0a8000b-c0 (gre: key=flow, local_ip=192.168.0.10,
remote_ip=192.168.0.11)
The flow table of br-int of HOST1 is as follows.
table=0, tun_id=0x2,in_port=5 actions=resubmit(,2)
table=0, in_port=4,dl_src=fa:16:3e:d0:51:39
actions=set_tunnel:0x2,resubmit(,1)
table=0, in_port=3,dl_src=fa:16:3e:f3:0d:ca
actions=set_tunnel:0x2,resubmit(,1)
(A) table=0, in_port=2,dl_src=fa:16:3e:f6:65:0b
actions=set_tunnel:0x2,resubmit(,1)
table=0, in_port=1,dl_src=fa:16:3e:bb:03:07
actions=set_tunnel:0x2,resubmit(,1)
(B) table=1, priority=8192,tun_id=0x2 actions=resubmit(,2)
table=1, priority=16384,tun_id=0x2,dl_dst=ff:ff:ff:ff:ff:ff
actions=output:5,resubmit(,2)
(D) table=1, tun_id=0x2,dl_dst=fa:16:3e:8c:4b:8e actions=output:5,resubmit(,2)
table=2, priority=8192,tun_id=0x2 actions=drop
table=2, tun_id=0x2,dl_dst=fa:16:3e:f6:65:0b actions=output:2
table=2, priority=16384,tun_id=0x2,dl_dst=ff:ff:ff:ff:ff:ff
actions=output:1,output:2,output:3,output:4
(C) table=2, tun_id=0x2,dl_dst=fa:16:3e:f3:0d:ca actions=output:3
table=2, tun_id=0x2,dl_dst=fa:16:3e:d0:51:39 actions=output:4
table=2, tun_id=0x2,dl_dst=fa:16:3e:bb:03:07 actions=output:1
The actual address of the floating IP is added to qg-8899056d-35, and
the packet is NATed and
routed in the netns.
An incoming packet from the external public network passes on
port2(tapa6339ea8-4d) of br-int.
The packet is matched the flow entry (A), and set tunnel id 2, and
goes to table1.
If the destination of the packet is vm1, the packet is forwarded to
port3 via (B) and (C).
If the destination of the packet is vm3, the packet is forwarded to
port5, gre port to HOST2, via (D).
Thanks,
Kaneko
