IGMP Proxy Configuration

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 is sent to the multicast router.

Downstream:

The interface data from the multicast router are sent to hosts in the multicast

group database.

UPnP Configuration

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.

RIP Configuration

RIP is an Internet protocol you can set up to share routing table information with other

routing dev

ices 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 Router, 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 Router). The ADSL Router 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.

ARP Table

The Address Resolution Protocol (ARP) is a computer networking protocol for determining

a network host's link layer or hardware address when only its Internet Layer (IP) or

Network Layer address is known. This function is critical in local area networking as well as

for routing internetworking traffic across gateways (routers) based on IP addresses when

the next-hop router must be determined.
