6.4 IGMP
Multicasting is useful when the same data needs to be sent to more than one hosts. Using
multicasting as opposed to sending the same data to the individual hosts uses less network
bandwidth. The multicast feature also enables you to receive multicast video stream from
multicast servers.
IP hosts use Internet Group Management Protocol (IGMP) to report their multicast group
memberships to neighboring routers. Similarly, multicast routers use IGMP to discover which
of their hosts belong to multicast groups. This device supports IGMP proxy that handles IGMP
messages. When enabled, this device acts as a proxy for a LAN host making requests to join
and leave multicast groups, or a multicast router sending multicast packets to multicast
group on the WAN side.
When a host wishes to join a multicast group, it sends IGMP REPORT message to the device’s
IGMP downstream interface. The proxy sets up a multicast route for the interface and host
requesting the video content. It then forwards the Join to the upstream multicast router. The
multicast IP traffic will then be forwarded to the requesting host. On a leave, the proxy
removes the route and then forwards the leave to the upstream multicast router.
The IGMP Proxy page allows you to enable multicast on WAN and LAN interfaces. The LAN
interface is always served as downstream IGMP proxy, and you can configure one of the
available WAN interfaces as the upstream IGMP proxy.
Upstream: The interface that IGMP requests from hosts are sent to the
multicast router.
Downstream: The interface data from the multicast router are sent to hosts in
the multicast group database.
Please check www.sitecom.com for up to date drivers & utilities, manuals and support
27
Field Description
IGMP Proxy Enable/disable IGMP proxy feature
Proxy Interface The upstream WAN interface is selected here.
Apply Changes
Click to save the setting to the configuration.
Undo
Discard your settings.
Sitecom ADSL2+ Modem DC-227
28
6.5 UPnP
The DSL device supports a control point for Universal Plug and Play (UPnP) version 1.0, and
supports two key features: NAT Traversal and Device Identification. This feature
requires one active WAN interface. In addition, the host should support this feature. In the
presence of multiple WAN interfaces, select an interface on which the incoming traffic is
present.
With NAT Traversal, when an UPnP command is received to open ports in NAT, the application
translates the request into system commands to open the ports in NAT and the firewall. The
interface to open the ports on is given to UPnP when it starts up and is part of the
configuration of the application.
For Device Identification, the application will send a description of the DSL device as a control
point back to the host making the request.
Field Description
UPnP Daemon Enable/disable UPnP feature.
Binded WAN
Interface
Select WAN interface that will use UPnP from the drop-down lists.
Apply Changes
Please check www.sitecom.com for up to date drivers & utilities, manuals and support
29
Click to save the setting to the system configuration.
6.6 RIP
RIP is an Internet protocol you can set up to share routing table information with other
routing devices on your LAN, at your ISP’s location, or on remote networks connected to your
network via the ADSL line.
Most small home or office networks do not need to use RIP; they have only one router, such
as the ADSL Modem, and one path to an ISP. In these cases, there is no need to share routes,
because all Internet data from the network is sent to the same ISP gateway.
You may want to configure RIP if any of the following circumstances apply to your network:
Your home network setup includes an additional router or RIP-enabled PC
(other than the ADSL Modem). The ADSL Modem and the router will need to
communicate via RIP to share their routing tables.
Your network connects via the ADSL line to a remote network, such as a
corporate network. In order for your LAN to learn the routes used within your
corporate network, they should both be configured with RIP.
Your ISP requests that you run RIP for communication with devices on their
network.
