Select a multicast IP address range for VXLAN network

  • In VXLAN, all the learning about the virtual machine MAC address and its association with VTEP IP address is performed through the support of physical network. Cloud Foundation on VxRail uses IP multicast by default to populate the forwarding tables in the VTEP.

    1. Assign a unique IP address range is assigned as the multicast IP address group in the range of 224.0.0.0 to 239.255.255.255. Each address in this range designates a multicast group.
    2. Do not use multicast addresses ranging from 224.0.0.1 to 224.0.0.255. These are reserved for routing protocols and other low-level topology discovery or maintenance protocols.
    3. Use administratively scoped addresses from 239.0.0.0 to 239.255.255.255 if the VXLAN deployment is within a company. This multicast address range is viewed as a private multicast domain.
    4. If VXLAN networks will be shared between administrative domains, the addresses should be assigned from the 232.0.0.0/8 (232.0.0.0-232.255.255.255) block.
