Chapter 6 WAN Setup The following table describes the labels in this screen. Table 17 Network > WAN > Internet Access Setup: Advanced Setup LABEL DESCRIPTION RIP & Multicast Setup This section is not available when you configure the ZyXEL Device to be in 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 ZyXEL Device sends and receives on the subnet. RIP Version Select the RIP direction from None, Both, In Only and Out Only. This field is not configurable if you select None in the RIP Direction field. Multicast Select the RIP version from RIP-1, RIP-2B and RIP-2M. 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). ATM QoS ATM QoS Type Peak Cell Rate Sustain Cell Rate Maximum Burst Size PPPoE Passthrough MTU MTU Internet Group Multicast Protocol (IGMP) is a network-layer protocol used to establish membership in a multicast group. The ZyXEL Device supports IGMP-v1 and IGMPv2. Select None to disable it. Select CBR (Continuous Bit Rate) to specify fixed (always-on) bandwidth for voice or data traffic. Select UBR (Unspecified Bit Rate) for applications that are non-time sensitive, such as e-mail. Select rtVBR (real-time Variable Bit Rate) type for applications with bursty connections that require closely controlled delay and delay variation. Select nrtVBR (non real-time Variable Bit Rate) type for connections that do not require closely controlled delay and delay variation. 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. 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 (MBS) refers to the maximum number of cells that can be sent at the peak rate. Type the MBS, which is less than 65535. If 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. The Maximum Transmission Unit (MTU) defines the size of the largest packet allowed on an interface or connection. Enter the MTU in this field. For ENET ENCAP, the MTU value is 1500. For PPPoE, the MTU value is 1492. Back Apply Cancel For PPPoA and RFC 1483, the MTU is 65535.

DESCRIPTION
RIP & Multicast Setup
This section is not available when you configure the ZyXEL Device to be in 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 ZyXEL
Device sends and receives on the subnet.
Select the RIP direction from
None
,
Both
,
In Only
and
Out Only
.
RIP Version
This field is not configurable if you select
None
in the
RIP Direction
field.
Select the RIP version from
RIP-1
,
RIP-2B
and
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).
Internet Group Multicast Protocol (IGMP) is a network-layer protocol used to establish
membership in a multicast group. The ZyXEL Device supports
IGMP-v1
and
IGMP-
v2
. Select
None
to disable it.
ATM QoS
ATM QoS Type
Select
CBR
(Continuous Bit Rate) to specify fixed (always-on) bandwidth for voice or
data traffic. Select
UBR
(Unspecified Bit Rate) for applications that are non-time
sensitive, such as e-mail. Select
rtVBR
(real-time Variable Bit Rate) type for
applications with bursty connections that require closely controlled delay and delay
variation. Select
nrtVBR
(non real-time Variable Bit Rate) type for connections that
do not require closely controlled delay and delay variation.
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 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.
MTU
MTU
The Maximum Transmission Unit (MTU) defines the size of the largest packet allowed
on an interface or connection. Enter the MTU in this field.
For ENET ENCAP, the MTU value is 1500.
For PPPoE, the MTU value is 1492.
For PPPoA and RFC 1483, the MTU is 65535.
