IGMP Message Handling
VLAN-enabled MVR handles IGMP messages for the following processes:
- Reports/Leaves:
Groups that belong to the MVLAN are processed in the MVLAN context only if received from receiver ports.
- Transparent Mode: Reports are transparently forwarded and are not used to learn group membership in the source VLAN. This ensures that IGMP messages do not alter group membership in the MVLAN, preserving VLAN isolation.
- Query: IGMP queries are handled according to standard IGMP snooping behavior.
- Multicast Data: By default, multicast data is only forwarded to router ports. Source ports that are not router ports must be manually configured as router ports to be included in the forwarding of multicast data.
