1. Would there be problem for VLAN backed logical router use case, since a chassis MAC is used as src MAC to send packets from router ports? 2. How about checking if tpa == spa to make sure GARP is always flooded? (not directly supported by OF) On Mon, Nov 11, 2019 at 5:32 AM Dumitru Ceara

[ovs-dev] [PATCH ovn v6] ovn-northd: Limit ARP/ND broadcast domain whenever possible.

2019-11-08 Thread Dumitru Ceara
ARP request and ND NS packets for router owned IPs were being flooded in the complete L2 domain (using the MC_FLOOD multicast group). However this creates a scaling issue in scenarios where aggregation logical switches are connected to more logical routers (~350). The logical pipelines of all
