2019-11-12 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
