11.6.2 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 Scenario 3 – APIC config steps.pdf attachment.
Connectivity is verified by pinging between the VMs shown in Figure 66. Since inter-EPG communication is
allowed using configured contracts, all VMs can ping all other VMs in the topology.
Figure 83 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.
