OVN supports FDB learning provided the logical switch port has addresses set to "unknown". But it only stores the MAC-logical port information and not IP. Please check this - https://github.com/ovn-org/ovn/blob/main/ovn-sb.ovsschema#L524 and https://github.com/ovn-org/ovn/blob/main/ovn-sb.xml#L4511 To answer your question, I don't think OVN supports MAC-IP learning the way you are expecting. We do have another table - MAC Binding in Southbound database, but that is learnt in the router pipeline. You can check that out here - https://github.com/ovn-org/ovn/blob/main/ovn-sb.xml#L3365 Thanks Numan > Thanks, > Jaspal > > ________________________________ > From: discuss <ovs-discuss-boun...@openvswitch.org> on behalf of Jaspal Singh > Dhillon <jaspal.dhil...@nutanix.com> > Sent: Wednesday, February 16, 2022 10:31 PM > To: ovs-discuss@openvswitch.org <ovs-discuss@openvswitch.org> > Cc: Avignan Chatterjee <avignan.chatter...@nutanix.com> > Subject: [ovs-discuss] Query wrt IPAM outside OVN > > Hello, > > Is it possible for OVS/OVN to learn MAC-IP bindings in a network, where the > IPAM is done outside of OVN (basically external IPAM) ? > We are exploring options to achieve it and one way is to snoop packets and > update CMS directly. > But if this is a solved problem in OVS community, can you please suggest how > to go on about it. > > Thanks, > Jaspal > _______________________________________________ > discuss mailing list > disc...@openvswitch.org > https://mail.openvswitch.org/mailman/listinfo/ovs-discuss _______________________________________________ discuss mailing list disc...@openvswitch.org https://mail.openvswitch.org/mailman/listinfo/ovs-discuss
