30 Dell EMC Networking OS10 Enterprise Edition Deployment Guide with Cisco ACI
9.3 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 17 through 19 in the attachment titled OS10EE Deployment Guide -
Cisco APIC configuration steps.
Connectivity is verified by pinging between the VMs shown in Figure 6. Since inter-EPG communication is
allowed using configured contracts, all VMs can ping all other VMs in the topology.
Figure 17 shows that the VM named app-01, located in a rack server, successfully pinging the VMs named
web-03 and db-04, which are on the servers.
