2 Multimedia Traffic Control with IP Multicast (IGMP) v2
NG
IGMP V2 NG Overview
IGMP, after being re-architected, is referred to as IGMP v2 NG, the next generation of IGMP
version 2. IGMP v2 NG is based on the existing working Multicast Listener Discovery (MLD) code
base and an event-driven architecture which enable easy enhancement and maintenance of the
code. IGMP v2 NG uses Multicast Traffic Manager (MTM) to program hardware filters and MAC
address.
The syslog hostname configuration is system-wide, not per syslog server.
