Figure 71: Optimized routing before moving VMs
In the traditional data center, we saw the chaos that resulted when a lot of VMs were moved. In an
optimized data center as shown below, the incoming traffic enters the Layer 2 domain where an
edge switch uses Inter-VSN Routing to attach an I-SID to a VLAN. The I-SID bridges traffic directly
to the destination. With VRRP Backup Master, the traffic no longer goes through the default
gateway; it takes the most direct route in and out of the network.
