DESCRIPTION

RIP & Multicast

 

Setup

 

 

 

RIP Direction

Select the RIP direction from None, Both, In Only and Out Only.

 

 

RIP Version

Select the RIP version from RIP-1, RIP-2Band RIP-2M.

 

 

Multicast

IGMP (Internet Group Management 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.

 

 

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

Maximum Burst Size (MBS) refers to the maximum number of cells that can be

Size

sent at the peak rate. Type the MBS, which is less than 65535.
