BUM Traffic: Hierarchical Two-Tier Replication

With hierarchical two-tier “destination,” replication is performed. The source transport node replicates the BUM packet to one single transport node hosted on another TEP subnet. This transport node will hold the MTEP that acts as a proxy TEP responsible for the replication to all other transport nodes in that TEP subnet that have a virtual machine that uses the NSX-T web segment (VNI=6000).

In Figure 5-32, VM A sends traffic to VM D, and ESXi A initiates the replication to all the MTEP hosts. In this case, the traffic will be forwarded to ESXi C, which was elected to be the “proxy” with an MTEP, and ESXi C will replicate the packet to ESXi D because ESXi D has a virtual machine that uses the NSX-T web segment (VNI=6000).

VM D will reply with its MAC address, and VM A will know where to send the packets.
