An IPv4 multicast address is a destination address in the range of 224.0.0.0 to 239.255.255.255. Addresses of 224.0.0.X are reserved. Because packets destined for these addresses may require VLAN flooding, devices d ...

    On both switch and router software images, IGMP snooping is either *,G based or S,G based. The hardware can either match the group address only (* G), or both the source and group (S, G) of the data stream. This is 32-bit IP address matching, not 23-bit multicast MAC address 01-00-5e-xx-xx-xx matching. When any port in a VLAN is configured for IGMP ...
