Hi Priyankar,
Thanks for the patch.
Can you please tell me the use case ?
Lets say a logical router lr1 has sw1 (10.0.0.0/24) , sw2
(20.0.0.0/24) and sw3 (30.0.0.0/24) and the corresponding
gw ports are bound to chassis ch1, ch2 and ch3 respectively.
Let's say we attach load balancers - lb1 (10.0.0.40:80 ->
20.0.0.40:80), lb2 (20.0.0.50:80 -> 30.0.0.50:80) and
lb3 (30.0.0.60:80 -> 10.0.0.60:80) to lr1.
If I understand correctly, routing for sw1 (10.0.0.0/24) is handled on
the chassis ch1 and so on for other switches.
This patch generates the below logical flows in the router pipeline
for load balancer lb1, lb2 and lb3
table=8 (lr_in_dnat ), priority=110 , match=(ct.new &&
!ct.rel && ip4 && ip4.dst == 10.0.0.40 && tcp && tcp.dst == 80 &&
is_chassis_resident("cr-lr0-sw1")),
action=(ct_lb_mark(backends=20.0.0.40:80);)
table=8 (lr_in_dnat ), priority=110 , match=(ct.new &&
!ct.rel && ip4 && ip4.dst == 10.0.0.40 && tcp && tcp.dst == 80 &&
is_chassis_resident("cr-lr0-sw2")),
action=(ct_lb_mark(backends=20.0.0.40:80);)
table=8 (lr_in_dnat ), priority=110 , match=(ct.new &&
!ct.rel && ip4 && ip4.dst == 10.0.0.40 && tcp && tcp.dst == 80 &&
is_chassis_resident("cr-lr0-sw3")),
action=(ct_lb_mark(backends=20.0.0.40:80);)
table=8 (lr_in_dnat ), priority=110 , match=(ct.new &&
!ct.rel && ip4 && ip4.dst == 20.0.0.50 && tcp && tcp.dst == 80 &&
is_chassis_resident("cr-lr0-sw1")),
action=(ct_lb_mark(backends=30.0.0.50:80);)
table=8 (lr_in_dnat ), priority=110 , match=(ct.new &&
!ct.rel && ip4 && ip4.dst == 20.0.0.50 && tcp && tcp.dst == 80 &&
is_chassis_resident("cr-lr0-sw2")),
action=(ct_lb_mark(backends=30.0.0.50:80);)
table=8 (lr_in_dnat ), priority=110 , match=(ct.new &&
!ct.rel && ip4 && ip4.dst == 20.0.0.50 && tcp && tcp.dst == 80 &&
is_chassis_resident("cr-lr0-sw3")),
action=(ct_lb_mark(backends=30.0.0.50:80);)
table=8 (lr_in_dnat ), priority=110 , match=(ct.new &&
!ct.rel && ip4 && ip4.dst == 30.0.0.60 && tcp && tcp.dst == 80 &&
is_chassis_resident("cr-lr0-sw1")),
action=(ct_lb_mark(backends=10.0.0.60:80);)
table=8 (lr_in_dnat ), priority=110 , match=(ct.new &&
!ct.rel && ip4 && ip4.dst == 30.0.0.60 && tcp && tcp.dst == 80 &&
is_chassis_resident("cr-lr0-sw2")),
action=(ct_lb_mark(backends=10.0.0.60:80);)
table=8 (lr_in_dnat ), priority=110 , match=(ct.new &&
!ct.rel && ip4 && ip4.dst == 30.0.0.60 && tcp && tcp.dst == 80 &&
is_chassis_resident("cr-lr0-sw3")),
action=(ct_lb_mark(backends=10.0.0.60:80);)
If a logical port of sw2 (20.0.0.4) sends any packet to 10.0.0.0/24,
then ideally the routing will be handled in ch1 since lr1-sw1 is
bound on ch1.
Now with the above logical flows, load balancing could happen in the
source chassis itself. Is that ok ?
Shouldn't this patch generate the flows like this for lb1, lb2 and lb3 ?
table=8 (lr_in_dnat ), priority=110 , match=(ct.new &&
!ct.rel && ip4 && ip4.dst == 10.0.0.40 && tcp && tcp.dst == 80 &&
is_chassis_resident("cr-lr0-sw1")),
action=(ct_lb_mark(backends=20.0.0.40:80);)
table=8 (lr_in_dnat ), priority=110 , match=(ct.new &&
!ct.rel && ip4 && ip4.dst == 20.0.0.50 && tcp && tcp.dst == 80 &&
is_chassis_resident("cr-lr0-sw2")),
action=(ct_lb_mark(backends=30.0.0.50:80);)
table=8 (lr_in_dnat ), priority=110 , match=(ct.new &&
!ct.rel && ip4 && ip4.dst == 30.0.0.60 && tcp && tcp.dst == 80 &&
is_chassis_resident("cr-lr0-sw3")),
action=(ct_lb_mark(backends=10.0.0.60:80);)
So that the LB NAT happens on the chassis where the distributed
gateway port for the LB vip subnet resides ?
Thanks
