21. Define the following
Multicast Listener Discovery (MLD) snooping enables a controller, service platform or access point to examine MLD packets
and make forwarding decisions based on content. MLD is used by IPv6 devices to discover devices wanting to receive
multicast packets destined for specific multicast addresses. MLD uses multicast listener queries and multicast listener
reports to identify which multicast addresses have listeners and join multicast groups.
MLD snooping caps the flooding of IPv6 multicast traffic on controller, service platform or access point VLANs. When
enabled, MLD messages are examined between hosts and multicast routers and to discern which hosts are receiving
multicast group traffic. The controller, service platform or access point then forwards multicast traffic only to those
interfaces connected to interested receivers instead of flooding traffic to all interfaces.

5.4.5.4.12Overriding a Cisco Discovery Protocol Configuration
Overriding the Network Configuration
The Cisco Discovery Protocol (CDP) is a proprietary data link layer protocol implemented in Cisco networking equipment. It's
primarily used to obtain IP addresses of neighboring devices and discover their platform information. CDP is also used to obtain
General MLD snooping parameters for the bridge VLAN configuration:
Enable MLD snooping to examine MLD packets and support content forwarding on this
bridge VLAN. Packets delivered are identified by a single multicast group address.
Multicast packets are delivered using best-effort reliability, just like IPv6 unicast. MLD
snooping is enabled by default.
Use this option to either enable or disable IPv6 unknown multicast forwarding. This setting
is enabled by default.
Multicast Router settings
Select the ge or radio interfaces used for MLD snooping.
Set the pim-dvmrp or static multicast routing learn mode. DVMRP builds a parent-child
database using a constrained multicast model to build a forwarding tree rooted at the
source of the multicast packets. Multicast packets are initially flooded down this source
tree. If redundant paths are on the source tree, packets are not forwarded along those
paths.
MLD Querier parameters for the profile's bridge VLAN configuration:
Select the option to enable MLD querier on the controller, service platform or access point.
When enabled, the device sends query messages to discover which network devices are
members of a given multicast group. This setting is enabled by default.
Define whether MLD version 1 or 2 is utilized with the MLD querier. MLD version 1 is based
on IGMP version 2 for IPv4. MLD version 2 is based on IGMP version 3 for IPv4 and is fully
backward compatible. IPv6 multicast uses MLD version 2. The default MLD version is 2.
Specify the maximum response time (from 1 - 25,000 milliseconds) before sending a
responding report. Queriers use MLD reports to join and leave multicast groups and receive
group traffic. The default setting is 1 milliseconds.
Specify an interval in either Seconds (60 - 300) or Minutes (1 - 5) used as a timeout interval
for other querier resources. The default setting is 60 seconds
