This object indicates IGMP Snooping support for
IGMPv3 as described below:
basic(1): Basic support for IGMPv3. IGMPv3 packets are
processed similar to IGMPv2 packets. In other words
Source list information is not used. Although this
does not break multicast traffic to IGMPv3 hosts,
it does not provide any other benefits such as Fast
Leave for IGMPv3 hosts, Explicit Host Tracking and
Source based filtering.
full(2): Full support for IGMPv3. Provides full IGMPv3
Snooping support. This includes processing of
IGMPv3 source list information along with group
information. Provides support for features such
as Fast Leave, Explicit Host Tracking and Proxy
Reporting and a potential to do Source based
filtering.
