RIP & Multicast

Setup

RIP Version Select the RIP version from RIP-1, RIP-2B and RIP-2M.

Multicast 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-nRT (Variable Bit Rate-non Real Time)

or VBR-RT (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.
