Figure 45: Optimized routing before moving VMs
In the traditional data center, chaos resulted after many VMs were moved. In an optimized
data center as shown in the following figure, 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 BackupMaster, the traffic no longer goes through
the default gateway; it takes the most direct route in and out of the network.
