WarpTwo Router - MultiCast
IP Multicast Features
User control over supported multicast routes.
Multicasting features are defined at the 'Logical Route'
level and are therefore destination sensitive not connection
sensitive.
IGMPv2
support.
WarpTwo supports standard IGMPv2 services (defined in
RFC 2236) but may be optionally configured to use IGMPv1 services.
User
control over IGMPv1 & IGMPv2 support.
The
user may enable IGMPv1 support using the ZyTrax Enterprise SNMP MIB. The
default is to use IGMPv2 services.
User
control over ‘membership query’ intervals.
The
use may control the frequency of IGMP membership queries via the ZyTrax
Enterprise SNMP MIB allowing optimization of LAN use.
Filtering
of Housekeeping and User Multicast traffic (Housekeeping Multicasts will not
keep Link open).
IGMPv1 or IGMPv2 messages are categorized as 'Housekeeping' and as such are NOT used in any calculations to keep links open or to add or remove capacity. Links will be
dropped only if there no user data traffic flowing.
