LABEL DESCRIPTION
RIP & Multicast
Setup
This section does not apply when you configure the Device to bridge mode.
RIP Direction RIP (Routing Information Protocol) allows a router to exchange routing information
with other routers. Use this field to control how much routing information the Device
sends and receives on the subnet.
Select the RIP direction from None, Both, In Only and Out Only.
RIP Version This field does not apply if you select None in the RIP Direction field.
Select the RIP version from RIP-1, RIP-2B/RIP-2M.
Multicast Multicast packets are sent to a group of computers on the LAN and are an alternative
to unicast packets (packets sent to one computer) and broadcast packets (packets
sent to every computer).
Devices use the IGMP (Internet Group Management Protocol) network-layer protocol
to establish membership in a multicast group. Select IGMP v1/IGMP v2/IGMP v3.
Select None to disable it.
MLD Proxy Select the version of MLD proxy (v1 or v2) to have the Device act as for this
connection. This allows the Device to get subscription information and maintain a
joined member list for each multicast group. It can reduce multicast traffic
significantly. Select None to turn off MLD proxy.
ATM QoS This section is available when the connection’s Virtual Channel field is set to an ADSL
option.
ATM QoS Type Select CBR (Continuous Bit Rate) to specify fixed (always-on) bandwidth for voice or
data traffic. Select UBR With PCR (Unspecified Bit Rate with Peak Cell Rate) for
applications that are non-time sensitive, such as e-mail. Select Non Realtime VBR
(Variable Bit Rate-non Real Time) or Realtime VBR (Variable Bit Rate-Real Time) for
bursty traffic and bandwidth sharing with other applications.
Peak Cell Rate Divide the DSL line rate (bps) by 424 (the size of an ATM cell) to find the Peak Cell Rate
(PCR). This is the maximum rate at which the sender can send cells. Type the PCR
here.
Sustain Cell Rate The Sustain Cell Rate (SCR) sets the average cell rate (long-term) that can be
transmitted. Type the SCR, which must be less than the PCR. Note that system default
is 0 cells/sec.
Maximum Burst
Size
Maximum Burst Size (MBS) refers to the maximum number of cells that can be sent at
the peak rate. Type the MBS, which is less than 65535.
PPPoE Passthrough If the encapsulation type is PPPoE, select this to enable PPPoE Passthrough. In
addition to the Device’s built-in PPPoE client, you can select this to allow hosts on the
LAN to use PPPoE client software on their computers to connect to the ISP via the
device. Each host can have a separate account and a public WAN IP address.
