Bridge Multicast Address - Cisco Small Business 300 1.1 Series Administration Manual

Address Table Commands
78-20269-01 Command Line Interface Reference Guide
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:
FDB mode IGMP version 2
mac-group MAC group
address
ipv4-group IP group address
ipv4-src-grou (*)
p
(*) 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 ipv4-group on
VLAN 2.
Console(config)# interface vlan
Console(config-if)#
