IP multicast routing enables a host (source) to send a single copy of data to a single multicast address. Data is then distributed to a group of recipients using a special form of IP address called the IP multicast group address. You can configure multicast on a tier-0 gateway for an IPv4 network to enable multicast routing.
- From your browser, log in with admin privileges to an NSX Manager at https://<nsx-manager-ip-address>.
- Select .
- To edit a tier-0 gateway, click the menu icon (three dots) and select Edit.
- Click the Multicast toggle to enable multicast.
- In the Replication Multicast Range field, enter an address range in CIDR format.
Replication Multicast Range is a range of multicast group addresses (GENEVE outer destination IP) that is used in the underlay to replicate workload/tenant multicast group addresses. It is recommended that there is no overlap between the Replication Multicast Range and workload/tenant multicast group addresses.
