3.2.2.1 Multicast Snooping
When the bridging mode is configured to be mesh, the Mesh
Point automatically snoops IGMP and MLD multicast protocols
in order to provide a better multicast experience for the Non-
Mesh Points (NMPs) it supports. The Mesh Point may also be
configured to subscribe to a multicast group on behalf of an
NMP. This is useful in cases where the NMP does not use
IGMP or MLD.
If VLANs are enabled on the FastPath Mesh Point (refer to
Section 3.11), you must associate each multicast group
subscription with the VLAN used for multicast traffic. To do this,
you must subscribe by specifying the appropriate
VLAN ID, in
addition to the Mesh Access interface for the stream. If a VLAN
ID of
0 is specified, the multicast group subscription will be
applied when VLANs are disabled.
Observe the multicast groups to which the MP is currently
subscribed (whether learned or configured) with
show:
> show mesh -multicast-groups
VLAN ID: 1, MAC Address: 33:33:00:00:00:fb
IP Address: FF02:0:0:0:0:0:0:FB
Interface: Ethernet1, vifIndex:3
Listener(Learned)
VLAN ID: 1, MAC Address: 33:33:00:00:49:49
IP Address: Not Available
Interface: eth0, vifIndex:6
Talker(Learned)
VLAN ID: 1, MAC Address: 33:33:ff:30:d7:c0
IP Address: FF02:0:0:0:0:1:FF30:D7C0
Interface: eth0, vifIndex:6
Listener(Learned)
NOTE: Only wire-
less BSSs config-
ured as Mesh Access
interfaces can be used
for multicast group sub-
scription. Do not specify
a Mesh Core interface.
To subscribe to a multicast group, use the add mesh
command. Identify the FP Mesh interface (-interface) by
specifying the wired Interface name or wireless BSS name for
the stream and specifying the multicast address for the group
by MAC or IP address. FPMPs can subscribe as multicast
listeners, talkers or both. If VLANs are configured and enabled
on the FPMP, enter a VLAN ID for the multicast group:
# add mesh -multicast-group -ip
<IpAddress>
|-mac
<MacAddress>
-interface
<InterfaceName>
|-bss
<BssName>
-vlan
<vlanID>
-mode listener|talker|both
You can force the MP to leave a configured multicast group
with the
del mesh command:
# del mesh -multicast-group -ip <
IpAddress
>|-mac <
MacAddress
> -interface <
InterfaceName
>|
-bss <
BssName
