IGMP in Windows Server 2008 and Windows Vista
Windows Server 2008 and Windows Vista support IP multicast sending, receiving, and forwarding through the TCP/IP protocol and, for Windows Server 2008, the Routing and Remote Access service.
TCP/IP Protocol
TCP/IP for Windows Server 2008 and Windows Vista supports IP multicast traffic in the following ways:
- To support host reception of IP multicast traffic, TCP/IP for Windows Server 2008 and Windows Vista is an IGMPv1, IGMPv2, and IGMPv3-capable host.
- To support host transmission and reception of IP multicast traffic, TCP/IP for Windows Server 2008 and Windows Vista supports the mapping of IP multicast addresses to MAC addresses for Ethernet network adapters as described in this chapter. For Token Ring network adapters, all IP multicast traffic is mapped to the Token Ring functional address of 0x-C0-00-00-04-00-00.
- To support the forwarding of IP multicast traffic, TCP/IP for Windows Server 2008 and Windows Vista supports multicast forwarding based on the setting of the EnableMulticastForwarding registry value and the entries in the TCP/IP multicast forwarding table. You can view the contents of the TCP/IP multicast forwarding table on a computer running Windows Server 2008 from the Routing and Remote Access snap-in or from the display of the netsh routing ip show mfe command.
In Windows Server 2008 and Windows Vista, IP multicast forwarding is controlled by the following registry value:
EnableMulticastForwarding <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< Code View: Scroll / Show All Location: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters Data Type: REG_DWORD Valid Range: 0-1 Default: 0 Present by Default: No
Nota: Desabilitar el firewall y ver que hay una ruta hacia la ip 224.0.0.0 (Windows dispone del comando route como linux).
