Multicast

  • VxRail depends on IPv6 multicasting to support device discovery during the cluster build operation and node expansion. The IPv6 is a private network that is isolated within the switches supporting the VxRail cluster in order to limit the impact on the data center network. Enabling MLD snooping and snooping querier is recommended on the physical switch to optimize multicast traffic.

    If your network infrastructure does not support IPv6 multicast, or if your network policy does not allow IPV6 multicast, you can choose to have the nodes ingested manually during the cluster build operation and during node expansion. This option is supported with VMware Cloud Foundation 4.2 or later, as this option depends on VxRail version 7.0.130 or later.
