Hi:
I'm working with OVS 2.13.2&OVN20.03.2,recently?I found OVN
LoadBalance not work as excepted(non-distributed).
Here is my configuration?refer to
https://hustcat.github.io/ovn-lb-practice/ and ovn.at and
https://www.ovn.org/support/dist-docs/ovn-nb.5.html ??
1?Create LS1 and vm1?vm2?vm3?vm4?vm1?vm2?vm3?vm4 connect to LS1
ovn-nbctl ls-add sw1
ovn-nbctl lsp-add sw1 lsp-vm1
ovn-nbctl lsp-set-addresses lsp-vm1 ?00:16:3e:eb:4d:10 21.21.21.21?
ovn-nbctl lsp-add sw1 lsp-vm2
ovn-nbctl lsp-set-addresses lsp-vm2 ?00:16:3e:b5:15:d4 21.21.21.22?
ovn-nbctl lsp-add sw1 lsp-vm3
ovn-nbctl lsp-set-addresses lsp-vm3 ?00:16:3e:97:fd:e3 22.22.22.21?
ovn-nbctl lsp-add sw1 lsp-vm4
ovn-nbctl lsp-set-addresses lsp-vm4 ?00:16:3e:d7:65:f8 22.22.22.22?
2? Create LR1 and connect LS1 to LR1.
ovn-nbctl lr-add lr1
ovn-nbctl lrp-add lr1 lr1-sw1 fa:16:3e:ed:dd:66 21.21.21.1/24
ovn-nbctl lsp-add sw1 sw1-lr1
ovn-nbctl lsp-set-type sw1-lr1 router
ovn-nbctl lsp-set-options sw1-lr1 router-port=lr1-sw1
ovn-nbctl lrp-add lr1 lr2-sw1 fa:16:3e:e0:0f:b7 22.22.22.1/24
ovn-nbctl lsp-add sw1 sw1-lr2
ovn-nbctl lsp-set-type sw1-lr2 router
ovn-nbctl lsp-set-options sw1-lr2 router-port=lr2-sw1
3? Create LS-Public and connect LR1 to LS-Public
ovn-nbctl ls-add public
ovn-nbctl lrp-add lr1 lr1-public fa:16:3e:94:87:b5 100.7.33.151/20(SNAT)
ovn-nbctl lsp-add public public-lr1
ovn-nbctl lsp-set-type public-lr1 router
ovn-nbctl lsp-set-options public-lr1 router-port=lr1-public
ovn-nbctl lsp-set-gateway-chassis public-lr1 chassis1,chassis2
4? Create virtual port of LSP-Vir on LS-Public
ovn-nbctl lsp-add public public-vir
ovn-nbctl lsp-set-addresses public-vir "4e:64:5e:4c:e5:68 100.7.33.152"
ovn-nbctl lsp-set-type public-vir virtual
ovn-nbctl set logical_switch_port public-vir options:virtual-ip=100.7.33.152
ovn-nbctl set logical_switch_port public-vir
options:virtual-parents=lsp-vm1,lsp-vm2,lsp-vm3,lsp-vm4
5? Create Loadbalancer lb1,lb backen is vm1?vm2?vm3?vm4?VIP is
100.7.33.152
ovn-nbctl lb-add lb1 100.7.33.152:1234 21.21.21.21:3000,21.21.21.22:3000,22.
22.22.21:3000,22.22.22.22:3000
ovn-nbctl --wait=sb -- --id=@hc create Load_Balancer_Health_Check
vip="100.7.33.152\:1234" -- add Load_Balancer . health_check @hc
ovn-nbctl --wait=sb set load_balancer . ip_port_mappings:
21.21.21.21=lsp-vm1:21.21.21.2
ovn-nbctl --wait=sb set load_balancer . ip_port_mappings:
21.21.21.22=lsp-vm2:21.21.21.2
ovn-nbctl --wait=sb set load_balancer . ip_port_mappings:
22.22.22.21=lsp-vm3:22.22.22.2
ovn-nbctl --wait=sb set load_balancer . ip_port_mappings:
22.22.22.22=lsp-vm4:22.22.22.2
check service_monitor all backend are online
6? Add lb1 to LS1?LS2 and LR1
ovn-nbctl ls-lb-add sw1 lb1
ovn-nbctl lr-lb-add lr1 lb1
my topo is:
My config:
When I run curl http://100.7.33.152:1234 from Client,it works,But all
traffic pass from NODE2 (SNAT chassis),it?s not distributed!
Is there anything I mis-config? By the way,where can I found examples of how
virtual port works with loadbalance?
