DESCRIPTION
"This MIB module defines objects that describe IGMP/MLD
snooping.
It provides remote network management system the ability
to manage the IGMP/MLD Snooping feature when snooping is
operating at the system and port level.
Virtual systems and related ports data can be accessed by
NMS using appropriate SNMP context.
E.g. in order to access data related to a particular L2VPN
bridge domain system, the user shall specify on the SNMP
request the SNMP context related to that particular bridge
domain.
Glossary of terms:
GMI - Group Management Interval; it controls when the IGMP/MLD
snooping expires stale group membership states.
L2VPN - Layer 2 Virtual Private Network.
IGMP - Internet Group Management Protocol.
MLD - Multicast Listener Discovery.
MRT - Max Response Time.
TTL - Time To Live.
PIM - Protocol Independent Multicast.
TCN - Topology Change Notification.
Querier - External IGMP/MLD router sending out queries which
are flooded in the system (e.g a bridge domain).
Internal Querier - Virtual Querier that solicits periodic
membership reports by sending IGMP/MLD
general queries out of all system ports.
Winner/Looser Querier - A system can only have one active
querier at a time, if the internal
querier receives queries from another
querier it performs querier election,
the lowest IP address wins.
G-Query - General IGMP/MLD Query.
Solicitation - a global leave message with a NULL group
multicast address, when the upstream router
