IGMP/VLAN Configuration Screen
The IGMP/VLAN Configuration Screen, Figure 43, allows the user to enable or
disable IGMP (Internet Group Management Protocol, RFC 2236) on selected
VLANs, or globally on all VLANs that are available.
IGMP provides a solution for handling multicast streams in layer 2 switching
devices. IGMP is for hosts on multi-access networks to inform locally attached
switches of their Multicast group membership information. This is performed by
hosts multicasting IGMP Host Membership Reports. Multicast switches listen for
these messages and then pass them to routers. This allows distribution trees to be
formed to deliver multicast datagrams.
Information from the IGMP packets is used to send the multicast stream only to
the end stations that request it. IGMP is enabled or disabled by VLAN, not port-
by-port.
The following multicast routing protocols are transparently supported and are
used only to detect the location of routers.:
•
DVMRP (Distance Vector Multicast Routing Protocol, RFC 1075)
•
PIM (Protocol Independent Multicast) version 1 and 2
•
CBT (Core Based Trees)
•
MOSPF (Multicast OSPF, RFC 1583)
