68 Dell EMC PowerEdge MX SmartFabric Configuration Guide with Cisco ACI
5.5 Verify connectivity between VMs
In ACI, by default, communication flows freely within EPGs, but not between EPGs. To enable inter-EPG
communication, contracts are configured on the APIC. This example is configured for unrestricted inter-EPG
communication as shown in steps 4.2.18 through 4.2.20 in the Section 4.2.
Connectivity is verified by pinging between the VMs as shown in Figure 61. Since inter-EPG communication is
allowed using configured contracts, all VMs can ping all other VMs in the topology.
Figure 61 shows the VM named app-01, located in a rack server, successfully pinging the VMs named web-
03 and db-04, which are located on MX compute sleds.
