Re: [ovs-dev] 答复: [PATCH v1 1/3] Add multipath static router in OVN northd and north-db

No problem Gao. Btw, give it a try if you want, and double check that's as we said. I dint't have time to recheck, and my memory doesn't use to be great ;-) On Sat, Sep 23, 2017 at 1:54 AM, Gao Zhenyu wrote: > Sorry for misleading, in my other testing, I ping the

Re: [ovs-dev] 答复: [PATCH v1 1/3] Add multipath static router in OVN northd and north-db

Sorry for misleading, in my other testing, I ping the IP(is a router port's IP) and saw packets go into a chassis(router are pined on this ovn-chassis by using option:chassis=x). So in that time I though the router should be only on a specific ovn-node if route was pinned. Miguel had told

Re: [ovs-dev] 答复: [PATCH v1 1/3] Add multipath static router in OVN northd and north-db

I think the S/N or E/W are not the matter we should considering now. The multipath implementation is based on the existing ovn workflows. If you can use route to dispatch traffics to different node/logical port, then the multipath can make it. Otherwise it must get bug in multipath. If the static

Re: [ovs-dev] 答复: [PATCH v1 1/3] Add multipath static router in OVN northd and north-db

May be I missed something, but when I tried setting logical routers into specific chassis, still the E/W traffic was handled in a distributed way (from original chassis to destination chassis without going through the router chassis), such chassis was only used for N/S, but may be I got something

But, if an ovn port in foo (chassis A) wants to talk to alice1 (chassis B), wouldn't all that E/W routing will happen virtually and the end result is just a tunneled packet between chassis A and chassis B ? What's the benefit of multipath there if the possible failing link is always the

You can take a look at this patch that implement a testcase : https://patchwork.ozlabs.org/patch/815475/ In the testcase, we have R1, R2, R3. R1 and R2 that are connected to each other via LS "join" in 20.0.0.0/24 network. R1 and R3 that are connected to each other via LS "join2" in

Re: [ovs-dev] 答复: [PATCH v1 1/3] Add multipath static router in OVN northd and north-db

Can you share an example of how this would benefit E/W routing. I'm just not seeing the specific use case myself out of ignorance. It'd be great if you could explain how would it work between several ports in the networks and routers (may be a diagram?) otherwise I can't be really helpful

Re: [ovs-dev] 答复: [PATCH v1 1/3] Add multipath static router in OVN northd and north-db

Thanks for the suggestions! Not all Logical port has a real ofp_port connect with it. And bundle_load/bundle actions need real ovs port. Especially in ovn router port, all router port are virtual port which just a number/reg in our ovs-flows. This implement of multipath can seperate ovn

Re: [ovs-dev] 答复: [PATCH v1 1/3] Add multipath static router in OVN northd and north-db

I'm not very familiar with multipath implementations, but would it be possible to use bundle( ouput action with hrw algorithm instead of multipath calculation to a register?. I say this, because if you look at lib/multipath.c lib/bundle.c you will find that bundle.c is going to consider the

Re: [ovs-dev] 答复: [PATCH v1 1/3] Add multipath static router in OVN northd and north-db

Thansk for the questions. the multipath_port can be set via ovn-nbctl. Like : ovn-nbctl -- --id=@lrt create Logical_Router_Static_Route ip_prefix=0.0.0.0/0 nexthop=10.88.77.1 multipath_port=[mp1,mp2] -- add Logical_Router edge1 static_routes @lrt This patch haven't implement a ovn-nbctl command
