the ipv4 mode, because there is no overlapping of IPv4 Multicast addresses in
these modes.
For each Forwarding Data Base (FDB) mode, use different CLI commands to
configure static entries in the FDB, as described in the following table:
The following table describes the actual data that is written to the Forwarding
Data Base (FDB) as a function of the IGMP version that is used in the network:
(*) Note that (*,G) cannot be written to the FDB if the mode is ipv4-src-group. In that
case, no new FDB entry is created, but the port is added to the static (S,G) entries
(if they exist) that belong to the requested group. It is recommended to set the FDB
mode to ipv4-group or mac-group for IGMP version 2.
If an application on the device requests (*,G), the operating FDB mode is changed
to
ipv4-group.
Example
The following example configures the Multicast bridging mode as an mac-group
on VLAN 2.
switchxxxxxx(config)# interface vlan 2
switchxxxxxx(config-if)# bridge multicast mode mac-group
