LABEL DESCRIPTION
RIP & Multicast
Setup
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).
IGMP (Internet Group Multicast Protocol) is a network-layer protocol used to
establish membership in a multicast group. The ZyXEL Device supports both IGMP
version 1 (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 VBR-RT (real-time Variable Bit Rate) type for
applications with bursty connections that require closely controlled delay and delay
variation. Select VBR-nRT (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.
