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 <[email protected]> on behalf of Jaspal Singh > Dhillon <[email protected]> > Sent: Wednesday, February 16, 2022 10:31 PM > To: [email protected] <[email protected]> > Cc: Avignan Chatterjee <[email protected]> > 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 > [email protected] > https://mail.openvswitch.org/mailman/listinfo/ovs-discuss _______________________________________________ discuss mailing list [email protected] https://mail.openvswitch.org/mailman/listinfo/ovs-discuss
